Contract Servicing

Servicing is forward-thinking in the prevention of equipment failure. Having an annual or bi-annual contract will help in the defence against system failure, preserving the life expectancy of water pumps and pressurised equipment.

    Expansion Vessels and Accumulators

    Pumpforce engineers can carry integrated application of programming for pressurisation units, pumps and cold-water booster set to optimum performance, giving the end-user peace of mind knowing that the equipment is running at its full potential and condition, increasing the life expectancy of equipment which in turn will help prevent faults keeping maintenance and energy cost down, eliminating costly down time of plant equipment.

    Pumpforce recognises the importance of expansion vessels and accumulators which play a vital role in the smooth operation of systems and products taking up system pressures, allowing the system to breathe. That is why Pumpforce engineers will service, set up and commission essential correct working pressure.

    Contract Servicing

    Pumpforce Servicing Options

    Pressurisation Unit Servicing

    Pressurisation Unit Servicing Bi-Annual / Quarterly Visit Annual Visit
    Isolate pressure unit and expansion vessel from system
    Test unit pumps for leaks and bearing fatigue, free impeller assembly if seized
    Test high and low alarms to BMS systems
    Inspect controllers for integrity and good electrical connection
    View fault log, investigate if needed. Reset all service counters
    Test solenoid valves opening and closing (where applicable)
    Test ball cock assembly and inspect condition of break tank water, clean if needed
    Inspect and clean any PRV’s coming off pressure unit. Re-calibrate after cleaning
    Drain associated expansion vessels and inspect air cushion
    Recharge vessel air cushion back to correct working pressure if needed
    Re-test unit after serving leave open up to system

    Booster Sets Servicing

    Booster Sets Servicing Bi-Annual / Quarterly Visit Annual Visit
    Individually inspect each pump for mechanical seal leakage and lime scale build up
    Note orientation of selected circulator pumps. Advise if incorrect
    Note any imbalance or acoustic noise with motors and pumps for fatigue and worn parts
    Visually inspect electrical wiring to inverter (where applicable)
    Inspect inverter programs, adjust if needed (where applicable)
    Inspect and test NRV’S. Essential for correct operation
    View alarm log and investigate (reset where applicable)
    Test each pump max head at closed valve against pump data design pressure
    Test pressure transducer settings against system gauges (modify if needed via controller)
    Test set, wake up sleep threshold along with run on timers (pumps start and stop feature)
    Test low suction sensors, making sure dry running protection is working correctly and enabled
    Test break tank floats, low and high (where applicable)
    Isolate accumulators and drain water off
    Inspect air pressure in accumulators and re-charge to suit correct booster working pressure (SP)
    Re-test booster after servicing, leaving set in to optimum condition open system in auto

    Heating Pumps, Shunt Pumps and Chilled Pumps

    Heating Pumps, Shunt Pumps and Chilled Pumps Bi-Annual / Quarterley Visit Annual Visit
    Inspect correct installation and rotation of pumps
    Test correct installation and rotation
    Visually inspect electrical wiring and connection to motor and inverter
    Inspect programs and settings, adjust to suit required value of system (where applicable)
    Visual inspection of mechanical seal for water leakage and limescale build up
    Note any imbalance or acoustics with motor and pump for fatigue and worn parts
    Grease bearings via nipples, and update programme (selected models only)
    All pumps to be left in optimum condition open system in auto
