Consultancy

SPP Energy specialise in energy saving services to pumping systems. Focusing SPP's considerable experience of pump design and operation together with our knowledge of Life Cycle service support & on-site pumps system assessment, enables us to provide advice and recommendations for improving pump system efficiency for existing and planned pump systems.

Training

Training

On completion of assessing and auditing the pump system, SPP offer solutions by mapping the pump to the system. This procedure involves providing the 'best fit' option for individual installations. Trimming impellers or fitting larger impellers may be the 'best fit' solution in some instances, whereas VSD's may be more appropriate for others. Through QS PSAT auditing, a better fit pump package may be identified.

System Modification

System Modification

Systems can often be modified over time without consideration for the installed pump packages. Pump system assessments may also identify opportunities for system modifications that will provide energy saving benefits and reduce the cost of ownership of the pump systems. Contact us for an assessment.

Accredited Pump System Assessment to ASME EA2

It is essential to take a view of the complete pump system. As detailed in ASME EA2 the fundamental starting point of any assessment is to understand the requirements of the system, what is the function of the system and what is the output performance?

Benefit can be gained from performance testing of pump sets, but unless the complete system is considered partial or inappropriate, conclusions can be reached resulting in costly exercises that do not offer the best returns in energy saving and resulting CO2e reduction. Recirculation through control valves and non-return valves can often be overlooked. Subsequent pump overhaul or upgrade can actually increase the system losses.

Oversized pumps can sometimes be improved by using variable speed drives (VSD) but an investigation is required into the system characteristics to determine how suitable this option may be. In high static head conditions, VSD may not be appropriate.


 

Pump Efficiency Testing

On-site efficiency testing is offered primarily using thermodynamic test monitors. Power is still measured via a power analyser. Thermodynamic testing offers a more accurate assessment of actual pump performance and is therefore used for detailed pump system assessments where accurate validation of energy savings achieved is often a contractual requirement.

This method of testing is, to a certain extent, "intrusive" in that suction and discharge probes are inserted into the flow via ½ BSP gate valve fittings. If these are not available they will be required as a system modification before testing can commence. This technique also provides a means of data collection for trending results. Fixed installation packages are available. Contact us for a quotation.


 

Pump Performance Testing

On-site pump performance testing can often provide valuable information regarding the actual point that the pump is operating at on its Q.H. Curve (head vs flow). Pumps are normally tested by the OEM against a client issued specification. This specification is often modelled or calculated rather than being an actual measurement of the installation system curve. On-site testing offers an early opportunity of establishing any discrepancies between the specification as issued to the pump OEM, and the actual characteristics of the system as constructed.

On-site fixed installation, condition monitoring packages are not always set up to measure actual pump performance; they tend to concentrate on the machine's mechanical condition and deterioration, rather than "is the pump operating at B.E.P.", or "is it in hydraulic distress"? SPP Energy offer on-site performance testing using conventional measuring techniques. Flow is measured with ultrasonic flow meters with readings being taken from site-installed flow meters where available and where relevant. Power measurement is recorded using a power analyser. Results can be compared with original OEM specifications for the pump and system.

Factory tests conducted during pump overhaul and/or upgrade, can provide further confirmation of the actual pump performance and highlight any discrepancies. Fixed installation packages are available. Contact us for a quotation.


 

Mechanical Integrity Checks Condition Monitoring

Once the pump has been mapped to the system and is operating as close to BEP as is possible within the system, meaningful condition monitoring can take place. It is always preferable to take a "foot print" of the pump in known good condition as this can be used as a datum against which deterioration can be measured. Issues to be checked include:

Alignment Physical condition
Vibration Gland leakage
Thermal Imaging Data logging
