TOP Multi Tech Submersible Multi-stage Well Pump (With Automatic Control & Pressure Vessel)

Description

TOP Multi Tech Submersible Multi-stage Well Pump with Integrated Fixed Speed Control & Pressure Vessel

INSTALLATION & USE

The Pedrollo TOP-MULTI-TECH Submersible pumps are recommended for pumping clean water and liquids that are not chemically aggressive for the materials from which the pump is made.

Because of their high efficiency and reliability they are suitable for use in applications such as domestic water supply from reservoirs, tanks or relatively deep wells, for drawing rain water from cisterns to water gardens or for use in irrigation systems, etc.

TOP MULTI-TECH pumps are fitted with an internal electronic device which starts the pump when the pressure of the system falls below 1.5 bar (eg. when opening a tap) and stops it when the flow falls below 3 litre per minute.
It protects the pump:
– against dry running;
– against starting too frequently;
– against blockage: after long periods of pump inactivity the electronic device starts the
pump every 48 hours for 10 seconds.

Comes with A 4ltr pressure vessel included in the price. (GWS/PWB4LX)

For the best operation of the Top Multi Tech pumps the installation of a pressure vessel is required. This helps avoid frequent pump start ups which can result in energy savings.
