Power Shower Pump Guide - What are single ended power shower pumps?

What are single ended pumps and when should they be used?

Single Ended Water Pumps operate on one end only as distinct from Twin Ended Water Pumps which are designed to simultaneously pump hot and cold water .

Single Ended Water Pumps are typically installed in applications where it is required to boost pressure and flow of hot and/or cold separately from normal domestic tank fed supplies to suitable terminal appliances/outlets in the house. (See Fig1. below)

QT45SE-2 shower pump for small house or flat power shower solution.

Pumping hot or cold water in a small house or flat where a relatively small increase in supply pressure and flow is required and any showering requirement does not involve pulse or champagne handset mode
Installed between a valve and shower outlet to pump blended water this pump is ideal for pressurising non restrictive type shower valves with single function handsets.

Electric Showers - Where the normal mains cold supply to the household is inadequate to provide sufficient water pressure to operate an electric shower properly, the problem can be resolved using a QT45SE to pump cold water from the cold water storage tank giving the shower a high flow contact pressure supply

QT80SE-2 shower pump for mediukm size house power shower solution.

Installed between a shower outlet to pump blended water this pump is ideal for pressurising non restrictive type shower valves with single or two function handsets.
Pumping hot or cold water in a medium size house where a relatively moderate increase in supply pressure and flow is required and any showering requirement does not include champagne shower mode

QT120SE-2 shower pump for large house power shower solution.

Installed between a valve and shower outlet to pump blended water this pump is ideal for pressurising non restrictive type shower valves with handsets that incorporate functions that include "pulse and champagne"
Pumping hot or cold water in a large house where a significant increase in supply pressure and flow is required and showering requirements involve pulse or champagne

All three Single Ended Pumps are available for Negative head power shower applications in fully automatic (AS), MSP or MSA variants. The family of pumps are all continuously rated, making them ideal when used in the AS mode for whole house pumping and can be purchased in pairs complete with the AS pump controllers as a "Whole House Pack".

It is recommended that a Whole House Pack is purchased if it is required to pump more than 6 terminal appliances.
