The QT80 is designed for pumping hot or cold water in a medium sized house where a moderate increase in pressure is required.
The QT Range are centrifugal pumps that have been designed to provide smooth power with minimal noise. The superior design of the Techflow QT Shower Pumps allows them to handle hot water at higher temperatures without the problem of cavitation (i.e. aeration of the water causing spasmodic loss of pressure at the shower head).
Techflow QT Shower Pumps can operate with the hot water temperature at 70°c, or 65°c where pump is installed above the hot water cylinder. The QT single ended pumps come in three sizes from 1.2 bar to 3.3bar and have a 3 year guarantee.
Negative Head Switching
A Negative Head situation exists where the pumped outlet (e.g. shower-head) is in a position that is level with or higher than the base of the cold water storage tank (eg in a loft conversion).
Since conventional pumps require some gravity flow to activate the pump switching mechanism, they cannot start under these circumstances and will require some form of external switching to initiate start-up. Techflow offers various solutions for achieving this.
AS (Automatic Switching)
A fully automated system which senses pressure drop when a tap or shower valve is opened. The unique system ensures that both hot and cold outlets can be operated independently using a single switching unit.
MSA (Manual Switching Airswitch)
Operates via flush-mounted push-button airswitch, operated once the shower valve/tap is open. Supplied with 5 metres of airline, pre-assembled. Extensions kits available.
MSP (Manual Switch Pull-Cord)
Similar in function to the MSA, but operates via a pull-cord switch, necessitating only minimal disruption to the bathroom environment.
• Dimensions 305 x 220 x 130mm
• Ideal for installing between a non-restrictive shower valve and shower outlet to pump blended water to a single or two function handset.
• 2.3bar
• To boost performance to more restrictive shower systems or provide enhanced performance to low restriction systems. Can be used with multi-function shower heads with pulse mode
