The Tolsen peripheral booster water pump 0.5HP is a robust, reliable and economical pump used principally for water transfer in domestic and small scale water transfer applications. The pump body is made from cast iron with a brass insert set into the front housing for improved starting performance and protection from jamming. The impeller is made from brass.

• Quiet operation due to the anti vibration system between shaft and impeller
• More compact
• More efficient motor with low energy consumption and lower operating temperature.
• Special paint which gives improved resistance against environmental corrosion
• Longer life

Pumps can be installed for manual or automatic control using either the unique ‘Press control’ unit or a pressure tank and switch. Also available is the integral ‘Hydrofresh’ version which combines a 24L horizontal diaphragm tank, pressure switch and gauge with pressure settings of 1.4 Bar for pump start and 2.8 Bar for pump stop.

MOTOR

Pumps are close coupled to a TEFC brushless induction motor designed for continuous operation. A thermal relay is provided in the windings to protect against electrical and mechanical overload and the pump can be connected directly to the mains power supply through a 10amp fuse or MCB.
