Yellow-blue Pumping Units

SPECIFICATIONS:
The special features of pumping units is that the plungers of the pump have tolerances and no seals are used in the units and special type of non return valves as against traditional ball valves are used, which gives much longer trouble free service.
Electrical Pumping Units work on 230Volts A.C. or 440 volts A.C.3 phase depending upon their capacity and these can be operated by hand in case of power failure.
The front panel accommodate pressure gauge, on/off switch, slow fast lever to control the rate of loading and indicator lamps.
Further in electrical units a micro switch fitted in the pressure gauge and a connected to a relay automatically cuts of the power supply to the unit when gauge capacity is reached.
A dummy pointer to record maximum load applied is fitted on the cover glass.
In hand operated pumping units, two plungers of different diameter are used.
The plunger with larger diameter pumps oil at faster rage and is used for initial loading.
Further load is easily applied by the second pump which has a smaller diameter plunger,
The lever for operation of the pump is sufficiently long to minimize efforts and these units are suitable for site use.
