Service Pumps Solutions can provide static and dynamic balancing services on single parts and on complete rotors. Every rotating machine has a rotating element, the dynamic part subject to imbalance. Generally, a rotor consists of a shaft and the components keyed to it such as impellers, washers, bushings, discs, etc. Imbalance is understood to be the non-homogeneous distribution of mass with respect to the rotational axis. Due to the centrifugal forces of rotation, vibration and noise can be generated, amplified by any increase in the number of revolutions. In order for the pump, during service at different rotational speeds (transient or at maximum load), to present vibration within acceptable parameters, it is necessary for the rotor is balanced in advance; this process is aimed at improving the distribution of mass of the rotating bodies with respect to the axis. In each rotor there will always be a residual, but acceptable imbalance within the reference standard parameters.

Imbalance can be classified into static, coupled and dynamic. In practice, only two types are considered: static and dynamic. The appearance, function of the rotor and the type of balancing affect the position of the correction planes and the choice of the balancing tolerance.

Static imbalance:

Static imbalance produces an effect under quiet conditions. Essentially, it occurs when the rotor's center of gravity is not coincident with the rotational axis. Positioned on two supports, the rotor oscillates on its own axis, moving the point of greatest mass to the lowest position due to the effect of gravity. For static balancing, generally vertical balancing machines are used and the correction is carried out on a plane.

Dynamic imbalance:

Dynamic imbalance occurs when the rotor set in rotation produces an effect. In this case the imbalances are infinitesimal, distributed along the entire rotational axis. In practice, this distribution can be grouped into two resulting imbalances which generally have different angular values and positions. To dynamically balance, horizontal balancing is used and the correction is performed on two selected planes.

For the detection in the field of dynamic rotor balancing with machines in service, Service Pumps Solutions can offer non-destructive methods employing the following techniques:
  • Vibration and waveform analysis
  • Vibration phase analysis
  • Visual inspection of components visible from the outside such as: transmission joint, balance fifth wheels, etc. (with stationary machines)

Advantages for the Client:

  • Minimize the vibrations induced by the machines to within acceptable parameters
  • Increased machine efficiency
  • Achievement of expected component life
  • Reduction or elimination of failure caused by imbalance
  • Operational safety


Condition monitoring is the process whereby the specific parameters of one or more machines are acquired and analyzed; facilitating advance recognition of an anomaly before it effectively becomes a fault. Anything that can be measured, acquired and transformed into mathematical language can be analyzed, controlled and improved. The most common monitoring parameters include: vibration, temperature, pressure, flow rate, voltage, current intensity, etc. Through condition monitoring techniques, with historical data and trends, Service Pumps Solutions uses predictive maintenance to determine the status of the machines and plan, together with the Client, planned maintenance and the supply of spare parts. The Condition Monitoring service offered by Service Pumps Solutions uses non-destructive techniques that are most frequently used on pumps, turbines, compressors, motors, partly completed machines, rotating and reciprocating machines in general.

Monitoring with portable analysis equipment
Monitoring with portable analysis equipment is performed by a technician who carries out measurements on specific points taken in succession (route-based) at predetermined intervals. The analysis can be carried out in real time, or later by transferring the acquired data to dedicated software. Depending on the criticality of the machines to be monitored, Service Pumps Solutions will suggest specific data acquisition rates (route-based). The Customer has the option of requesting a timely predictive analysis or, in anticipation of repeated deadlines, Service Pumps Solutions offers dedicated contract services.
Monitoring techniques offered by Service Pumps Solutions with portable analyzers:

  • LUBRICANT ANALYSIS (tribological analysis)
  • ULTRASOUND ANALYSIS (detection and analysis of compressed air leaks)

Monitoring with fixed instruments (Industry 4.0)
Generally, monitoring with fixed instruments is performed solely on critical machines within equally critical processes. In this case, monitoring is performed continuously and alarm thresholds are triggered when a parameter drifts towards the critical threshold. This monitoring system with fixed instrumentation integrates perfectly with more structured logics and Industry 4.0 systems.
Monitoring using fixed contact instruments can be carried out in two ways:

  • Wired monitoring with fixed contact instruments.
    The sensors are mounted directly on the machine and the sensor leads connected to the analysis system.
  • Wireless monitoring with fixed contact instruments using a transmitter and remote receiver.
    The sensors are installed directly on the machine and, via a connected transmitter, sensor data is sent to a remote receiver over a wireless connection.

Advantages for the Client:

  • Know the status of the machines
  • Coping with conditions that reduce longevity before they turn into a breakdown, simultaneously avoiding the consequences

The motion is transferred from drive motor to operating component via a coupling with a transmission joint. In order for the machines to operate optimally, within permissible vibration parameters, the alignment of the axes must be guaranteed by a correct coupling of the transmission joint, performed using appropriate measurements with specific instruments.

Misalignment of the axes can originate from several points, including incorrect assembly of a joint, poor fastening, an operational displacement of the axis or due to thermal expansion.

The consequences of misalignment include:

  • Increase in vibration amplitude
  • Reduction of component life (bearings, joints, lubricants, etc.)
  • Increased risk of breakage
  • Risk to operators
  • Economic losses due to production downtime and emergency maintenance

According to the operating conditions of the machines and the type of transmission joint, Service Pumps Solutions adopts the following axis alignment techniques:

  • Straight edge and feeler gauge - accuracy ≥ 0.1 mm
  • Dial gauge - accuracy ≥ 0.01 mm
  • Laser - accuracy ≥ 0.001 mm

Before each alignment, the soft foot condition is checked and, if present, corrected. In addition, for detection in the field of axis alignment with machines in service, Service Pumps Solutions can offer non-destructive methods using the following techniques:

  • Vibration and waveform analysis
  • Vibration phase analysis
  • Infrared thermography
  • Strobe lamp
  • Visual inspection


Revamping technique:

With the Revamping technique, Service Pumps Solutions offers the option of modernizing and making obsolete pump units and plant economically viable for customers who intend to maintain existing systems.


Retrofitting technique:

With the retrofitting technique, Service Pumps Solutions offers not only the option to modernize the performance of pump units and systems, but also improve upon their original ‘stock’ version. Through retrofitting, it is possible to add new devices, automation systems, advanced materials and more reliable components to obtain greater functionality and improved performance.


Service Pumps Solutions offers, among its main services, Reverse Engineering. It consists of the swift analysis of an object of any shape and material, in order to reproduce a new component of similar functionality or technological improvement – in this case also increasing its efficiency. This technique is often used when the obsolete component exhibits damage or wear, even up to 80%, or when it is no longer possible to find the original spare part on the market or due to very long lead-in times.

The Reverse Engineering techniques adopted for the production of non-OEM spare parts include:

  • Optical digitization systems
  • Analogue and digital measuring instruments
  • Chemical and structural analysis - FEM modeling finite element simulation
  • Project and drawing implementation

Technologies and supplies to support Reverse Engineering include:

  • ‘Lost’ plug and mould production techniques
  • Semi-finished products by foundry casting or by forging
  • Semi-finished products for trade
  • NDT (non-destructive testing)
  • Thermal treatments
  • Products finished by mechanical processes incorporating interrupted or continuous machining – manual or CNC
  • Surface coatings
  • Static and dynamic balancing


In addition to the common methods of producing non-OEM spare parts, according to particular needs and following an accurate feasibility study of the component to be replicated, Service Pumps Solutions can supply components produced by the Additive Manufacturing technique. Additive Manufacturing is a technique that can be used to build very complex components and of different types of material from polymers to metals. The additive process starts with a digital 3D model converted into a usable format for processing. The base material is deposited, and then progressively built up layer by layer similar to a common printer.

Why use additive manufacturing?

Sometimes, the necessary component is not available when needed, or is out of production and therefore no longer available. In these cases, or to improve the design, additive manufacturing can also represent the opportunity to recreate the same component to offer greater efficiency and reliability. Components can be made using original construction drawings or a design obtained with the help of Reverse Engineering. Additive manufacturing is more convenient for small production runs and rapid prototyping, where the process helps to contain economic expenditure.

In particular, after being made, the item can undergo other treatments and processes if necessary, including: thermal or chemical treatments, finishing processes using machines for de-burring, turning and milling, etc.

Advantages for the Client:

  • Reproduce a geometrically complex replacement improved from the topological point of view
  • Short lead times for small quantities and complex shapes
  • Partial reconstruction of one or more components forming part of a single more complex unit


For all types of pumps, valves, rotating machines and auxiliary systems, Service Pumps Solutions can supply original and non-OEM spare parts or new complete motor / pump skids of any brand.
