Heating, also known as Circulator, pump are one of the most widely used pumps in the world and are simple, effective and reliable. In a standard set up water enters the pump via a horizontal pipe, goes through the impeller and – using centrifugal force – is flung out a vertical discharge.
These can be found with glanded or glandless motors, otherwise knowns as canned motors. Smaller canned inline pumps typically come as standard with the motor mounted inverter drives. Inline pumps are normally available in single or twin head, which can be configured to automatically swop duties.
The HWS (hot water system) pumps are available bronze or stainless.
Circulator pumps are used to overcome the resistance in the pipework and valves to ensure even circulation or distribution of heat or hot water. Old belt drive and fixed speed systems can be easily upgraded to new energy-efficient systems with payback times from 6 to 36 months, depending on application (link to energy savings page). In addition to saving energy, this can be a cost-effective way of upgrading your system. Let your energy savings pay for your upgrade.
