Shielded circulation pump series

Product Introduction

       OPA is a closed rotor type, ie the pump and the generator form an integral unit without a shaft seal with only two washers for sealing. The bearing is lubricated by the pumped liquid.

        The product eliminates the motor blades and ball bearings, the use of new ceramic bearings, ceramic bearings to reduce the mechanical noise of the rotor, the stator with a stainless steel sleeve seal, the work of the machine cavity any of its water, that is bearing lubrication and cooling, the province To the mechanical seal, to solve the pump leak, the pump small size, light weight, reliable performance, long life, in addition to household water pressure, can also be used for home heating with hot water circulation, such as solar water heaters, Central air conditioning and other industries can be used as machinery and equipment of the circulating pump, such as sealing machine, water machine and other supporting the use of.

Main Purpose

Application

        The shielded circulating water pump is designed for hot water systems. The pump can also be used for household life hot water circulation and cooler and air conditioning system liquid circulation.

Heating

        For centralized and regional heating systems, use OPA pumps. QPA can run at three speeds. Pumps are mainly used for single and double pipe heating systems, but are also suitable for, for example, hybrid circuits in large systems.

Floor heating

        For the floor heating system, it is recommended to use bronze OPA pumps, because the liquid is usually vaporized, will corrode the ordinary cast iron pump pump.

Life hot water

        Can be connected with an ON / OFF timer switch to save energy, ON / OFF timer switch can control the pump on / off to ensure that the pump in the need for hot water when running.

For cooling and air conditioning systems, use standard OPA type according to model / size.
