TOP MULTI
Multistage vertical submersible drainage centrifugal pumps with lower suction.
The extended rotor shaft is common for the motor and the pump (monoblock version). The pump shaft seal is secured from the side by a simple STA-12R SIC mechanical seal and by the STA-13R mechanical seal by the electric motor. Both mechanical seals are lubricated and cooled by a permanent oil filling. The closed submerged electric motor is located at the top of the pump and is cooled by a pumped liquid. The impellers on the shaft are rotated inside the beam diffuser, which directs the fluid from one impeller to the suction opening next. The liquid thus passes through the series of impellers into the discharge opening. Each impeller, diffuser, and cell body form a single step that increases the pressure of the liquid by the same value. The TOP MULTI pump delivery port has a standard 1¼ "male thread with a hose nipple.
The suction is located on the lower edge of the pump, covered with fine ribbing and a stainless steel sieve with a throughput of mechanical impurities up to ø 1,3 mm.
As a result 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. Suitable for use with clean water and liquids that are not chemically aggressive towards the materials from which the pump is made.
• 10 m maximum immersion depth (with a sufficiently long power cable)
• Passage of suspended solids up to Ø 1.3 mm
• Suction down to 22 mm above ground level
• Continuous service S1
