Side Channel Pumps The solution for critical conditions VERSA pump is a self-priming side channel pump capable of handling gas along with the medium and operates at a low noise level. PS pumps are used for problem-free pumping of clean liquids at unfavourable suction side conditions. They are also very suitable for positive suction heads below,5m. PS pumps provide the most appropriate solutions for liquefied gases, liquids under vapour pressure, refrigerants and especially PS applications. PSC MODEL Side channel designs fill the hydraulic performance void between positive displacement pumps and centrifugal pumps. Fully open ìstarî impellers interact with the side channel casing creating an intense transfer of energy to the pumped liquid or liquid / gas mixture. The corresponding pressure increase (pump head) equals 5 to 1 times the amount generated by a similar size centrifugal pump at the same RPM.

Working Principle of Pump The design of the side channel pump allows for the transfer of liquid-gas mixture with up to 5% vapor; therefore eliminating possible air or vapor locking that can occur in other pump designs. A special suction impeller lowers the NPSH requirement for the pump. The side-channel pump design is similar to a regenerative turbine in that the impeller makes regenerative passes through the liquid. However, the actual design of the impeller and casing as well as the principles of operation differ greatly. The side-channel pump has a channel only in the discharge stage casing (A) and a flat surface which is flush with the impeller on the suction stage casing (B). A star-shaped impeller (C) is keyed to the shaft and is axially balanced through equalization holes (D) in the hub of the impeller. The liquid or liquid/vapor mixture enters each stage of the pump through the inlet port (E). Once the pump is initially filled with liquid, the pump will provide a siphoning effect at the inlet port. The effect is similar to what happens in water ring pumps. The water remaining in the pump casing forms a type of water ring with a free surface. A venturi effect is created by the rotation of the impeller and the free surface of the water, thus pulling the liquid into the casing. After the liquid is pulled through the inlet port, it is forced to the outer periphery of the impeller blade by centrifugal action. It is through this centrifugal action that the liquid is accelerated and forced into the side channel. The liquid then flows along the semicircular contour of the side channel from the outermost point to the innermost point until once again it is accelerated by the impeller blade.

PSC Model Pumps Side Channel Pumps - type PSC Pumps of the series PSC are horizontal and self-priming, side channel pumps with a NPSH inducer stage suitable for handling liquids which do not contain solid or abrasive matter. The NPSH inducer stage allows the pump to operate on the suction side under unfavourable conditions and at positive suction heads lower than.5 m. The range comprises of six sizes each with 1 to 8 hydraulic stages whereby an optimum rating is obtained, ensuring the pump selected meets the required capacity and head. Model: PSC (With Cartridge Mechanical Seal) The different material possibilities with uniform dimensions and performance characteristics as well as the standard exchangeable components, coupling with mechanical seal, packing gland and cartridge seal make the PSC particularly recommendable. The pumps of the PSC /LS series have a retaining stage to avoid the dry running by controlling the liquid level in the pump. This design is especially developed for the handling of liquids under vapour pressure or when pumping from underground tanks. Model: PSC (With Mechanical Seal) OUTLET INLET Model: PSC (With Packing Gland) PSC - 6 Model: PSC (With Liquid Sensor) Side Channel allows for greater pressure generation per stage over normal centrifugal pump of the same size and speed Sealing options available are Packing Gland, Mechanical Seal or Cartridge Seal. Flanges options available are DIN and ANSI 15 & 3 norms. This impeller allows PSC Pumps to handle NPSH requirements of less than,5 meter.
