A booster pump is used in conjunction with a storage tank to provide sufficient water flow and pressure to meet system demand:
SELF PRIMING JET PUMP
- Normally a cast iron pump that is surface mounted and connected to the bottom outlet of the storage tank.
- These pumps are generally less expensive than the submersible type but can have a shorter life due to internal corrosion during the winter months when they must be drained and are much noisier in operation.
- A stainless steel pump that is installed inside a surface mounted or buried tank. This type of pump is very quiet in operation and has a very long service life.
VERTICAL MULTI STAGE
- A pump which has a frame constructed from cast iron and a body of stainless steel. These pumps are surface mounted and connected to the bottom outlet of the tank and are used where the system flow rate and pressure exceeds that which can be provided by a submersible pump.
ELECTRONIC SPEED CONTROLLED
- This type of pump has an electronic pump controller be mounted on top of the pump (Vertical Multi Stage) or wall mounted (Submersible).
- This unit manages the pump performance by automatically adjusting the pump duty to meet demand. This will result in both a saving in energy and prolong pump and system life.
- The initial cost of this type of pump is much higher than the aforementioned pumps but fitted as part of a larger system can result in significant energy savings over a period of time.
