Positive Head Shower Pumps (Twin Impeller)

If you’re suffering from low water pressure on both your hot and cold supplies then a twin impeller will definitely improve the situation. They boost the flow of both feeds of water to give you a more powerful water supply. It’s not all or nothing either, you can purchase pumps with a lower bar pressure (less than 2.0 bar) for a low to medium boost or something with a higher bar pressure (2.0 bar and over) for a larger boost. This selection of pumps in particular are positive head which means they’re suitable for use where your outlet (e.g showerhead) is lower than the outlet on your cold water storage tank (usually fitted in the loft).

Grundfos Amazon 2.0 Bar Twin Impeller Positive Head Pump - STP-2.0 B

Grundfos Amazon 2.0 Bar Shower Pump

This pump was straightforward to install, it looks good, and functions very effectively. Even the Grundfos packaging is well designed! It comes with 4 push-fit 22mm flexible adapters. These dont have integral isolation valves, but this wasnt an issue for me because my installation already had adequate means of isolation and drainage. The brass construction and continuous rating make this unit more expensive than plastic alternatives, but hopefully this will pay off in the long term.

A powerful pump

With the help of my plumber I selected this pump to replace an existing 2 bar pump and its performance is by far better than that of the previous pump even though it is sited in the loft and a long way from the hot water cistern (the worst possible place for a shower pump). I am very pleased with the purchase. It is also quieter than the previous pump.

Grundfos Amazon 2.0 Bar Twin Impeller Positive Head Pump - STP-2.0 B

Previously had 1.5 single model.That developed a leak after 11years and a second shower added in November.This model is a lot neater and certainly quieter,2.0bar twin impeller is a big improvement !! ORdering was simple and delivered as promised. Excellent service alround and after sales follow up. Will definitely use you again.

Fantastic domestic shower pump

A reliable and robust shower pump from a respected pump manufacturer. Easy to install with integrated isolation valves in the connection hoses and push fit pipe connectors. It’s brass construction promises years of trouble free operation. Well worth the cost.

Stuart Turner Showermate Shower Pump 2.6 Bar Twin Impeller Positive Head- 46431

Shower Pump

Delivery time fast - Price surprisingly cheap - pump quiet, powerful and easily fitted and hopefully reliable. Only criticism delivered when we were out and the delivery company left it outside in the rain.
