    SDP

    Applications and Installation

    The SDP pumps are regarded as one of the best pumps for deep well. In fact, they consist of two pumps connected in series, one is ejector-pump and the other is a centrifugal pump. The ejector pump is lowered in well and connected to the centrifugal pump body by two pipes. These pumps are suitable for pumping clean water and chemically non-aggressive fluids. They are extremely reliable, economical and simple to use widely applied in domestic applications and the automatic distribution of water from small and medium-sized surge tanks, forming an automatic booster system to supply water. The most remarkable character is that they can be used to supply clean water from an extremely deep well. To ensure adequate counter-pressure, it is always installed with a foot valve and a filter on the suction opening. Pumps should be installed in a covered area, protected against the weather.

    STPS

    Applications and Installation

    The STPS series are self-suction pumps, with peripheral impeller containing numerous radial blades in its edge, self-priming because of the particular design of the pump body which is with a small tank, water is thrown outwards by centrifugal motion caused by the impeller. Then the water rotates with the impeller, generating high pressure. These pumps have a compact size and are very economical, finding the most different operating requirements such as supply water from well, pool and so on, increase the water pressure in the pipe garden sprinkling or clean washing. Pumps should be installed in a covered area, protected against the weather.
