Household Pressure Systems

With so many pump types and models available, which pump is suitable for my application? Let an Aldgate Pump sales assistant help you select the right pump for you. We can show you:
• The most efficient design to minimise your electricity bill
• Pump features and products to minimize pump cycling and wear
• Pump capable of providing enough pressure for filtration and water treatment systems

Household Water Pressure systems
• Large range of multistage and jet pumps available
• Run dry protection
• Stainless steel models available

Submersible pump Household pressure systems
• Have you considered a submersible pressure system?... the pump is installed in the water tank!
Benefits include:
• No priming or relying on foot valves that can wear out or block up
• Quiet - due to the pump location underwater in the water tank
• Most models can run even partly submerged

Variable speed Household pressure systems (Constant Pressure)
• A Variable speed pressure system enables true “constant pressure” in the pipe systems
• No large fluctuations in pressure
• A variable speed pump adjusts the speed of the pump so as to constantly provide users with the same pressure,
even when demand for water changes
• Because the pumps speed depends on water demand, when running at reduced speeds, it is possible to save
up to 30% of power (based on pump affinity laws), compared to a standard pump of the same size. With the ever
increasing cost of electricity, over time, these pumps are cost efficient, not to mention the environmental
benefits of reducing energy
