Pressure sets and automatic pump control
These compact pressure boosting sets comprise of a water pump and controls to increase the poor pressure of potable or clean water to equivalent mains pressure for many uses such as domestic or agricultural water supply, rainwater harvesting, irrigation, car washing or connecting to industrial process machines. The water pressure can be adjusted within the limitations of the pump for even greater flexibility and to individual requirements. Water can be used from wells, tanks, shallow boreholes, spring catchments and harvested rainwater.
Their versatility and ease of installation lend themselves to 1001 uses, all being economical to run and inexpensive to buy.
1: PM46 Pump with PressControl. Such an arrangement is useful where space is limited and no buffering of supply is needed.
2: City IC50 Water Pump carries a compact 24 litre vertical pressure vessel as a quiet, economical domestic pressure-boosting set.
3:Jet 50 above a 20 litre Horizontal Vessel allows an alternative configuration. It has purpose-designed brackets so that the pump can be mounted on top. A braided pressure hose is required to link the two.
4: Twin Vertical Multistage Pumps. The 2GP Ebara pressure booster sets, in standard versions, can be used for residential, commercial, industrial and agricultural applications, namely for: water lifting or handling,cooling, heating, irrigation, washing systems. The liquid carried can be: clean water, drinking water, rainwater, well water, mixed water, provided it does not contain solids or fibres in suspension and is free of aggressive chemical substances. The pressure vessel will be sized to suit the application and will be sited alongside.
5: The GPE unit is designed to work with one pump controlled by a frequency converter VLT (inverter) whilst the others are triggered directly. The thus-configured unit can be used to keep pressure in the water main constant. As mains pressure varies, the pump controlled by the VLT (inverter) varies its speed of rotation to restore pressure to the set value. If the amount of water being drawn exceeds the pump’s capacity, the second pump is triggered directly and, at the same time, the VLT-governed pump enters control mode to keep water pressure at the set value. The same goes for all the unit’s component pumps. When drawing has stopped, the VLT-governed pump reaches minimum rotation value and then stops after a few minutes, making for considerable energy savings.
6: Press-O-Matic. Inverter for electric pump control. It controls the starting and stopping of the electric pump and modulates the motor rotations according to the water request from the system.
1: A PressControl coupled with a PM46 Pump
2: City IC50 Pump and 24 litre vertical vessel
3: Stainless Steel City Jet Pump mounted above a 20 litre vessel.
4: Ebara Twin Booster Set using vertical multistage pumps.
5:GPE Unit controlling 3 pumps.
6: Press-O-Matic, individual motor inverter.
