Energy Saving Inline Circulating Pump

This circulation pump control module allows for proportional pressure mode, constant speed mode or constant pressure mode depending on system requirements. There's also automatic mode and night mode. This is easily selected; the operator can switch between pump curves

XH series of high efficiency inline circulating pumps are designed for applications involving hot and cold water, these include; industrial and civil heating systems, air conditioning, HVAC and closed-circuit cooling.

Pumped fluids must be clean, free of oils, contain no solids and be non-flammable.

Compatible fluids include; hot water, cold water and water and glycol mixtures (check compatibility with glycol concentrations over 20%).

The acceptable fluid temperature range is between 2°C and 110°C, the ambient environmental temperature must not exceed 40°C.

XH range is fitted with a cutting-edge high efficiency motor that reduces energy consumption during operation.

Standard materials are:

Pump casing - Cast iron

Impeller - Polyamide

Shaft - Ceramic

Bearings - Ceramic

Rotor can - Stainless steel 

Additional product details:

1 permanent magnet technology for high energy efficiency

4 Automatic air venting
5 Compact and lightweight
6 170-260V Single Phase 50Hz or 60Hz motors
7 IP67

How do I know what size circulating pump is best for my system?
The standard information such as fluid, flow rate, head/pressure, power supply and required control features are important when selecting a circulating pump. However, it is also important to know the flange to flange dimensions of the existing pump. If it is a new application, then the available space will be required.

Can this pump run dry?
No, definitely not! Centrifugal pumps will incur damage even after short periods of dry running. The mechanical seal will be destroyed, and this will cause the pump to leak. There is also the possibility that the motor will burn out. Our advice is to ensure that the pump has a flooded suction or always make sure that the pump casing and inlet pipe are filled with water; one way of ensuring this is to fit a check valve on the inlet line to stop water escaping when the pump is inactive. Another way of protecting the pump is to fit a dry running device, this will turn the pump off if it detects that that no fluid is entering the pump. If you think that dry running is inevitable, then please speak to us and we will try to select a more suitable pump for your application.

How do I know what pump materials are correct for my application?
Firstly, always check the compatibility of the materials available against the fluid being pumped. The main materials to check are the pump casing, impeller, o-ring and mechanical seal. It may be that more than one material is suitable for your fluid and selection could be based on the application type. For instance; cast iron, bronze and stainless steel are all suitable for fresh water. If it is a simple transfer application, then the most cost-effective material cast iron will be best. However, if it is a sanitary application, then stainless steel or bronze are better choices.
