General InformationWhat is a Side Channel Pump?The design of the side channel pump allows for the transfer of liquid-gas mixtures with up to 50% vapor; therefore eliminating possible airor 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 achannel 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, thepump will provide a siphoning effect at the inlet port. The effect is similar to what happens in water ring pumps. The water remaining in thepump 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 ofthe 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 thiscentrifugal action that the liquid is accelerated and forced into the side channel. The liquid then flows along the semicircular contour of theside channel from the outermost point to the innermost point until once again it is accelerated by the impeller blade. The liquid movesseveral times between the impeller and the side channel. Thus the rotating impeller makes several regenerative passes until the liquidreaches the outlet port. The speed of the impeller along with the centrifugal action impart energy to the liquid through the exchange ofmomentum, thus allowing the pump to build pressure.
The side channel leads directly to the outlet port (F). At the outlet port, the main channel ends and a smaller mini-channel (G) begins. At thepoint where the mini-channel ends, there is a small secondary discharge port (H) level with the base of the impeller blades.
As the liquid is forced to the periphery through centrifugal action due to its density, the vapor within the liquid stream tends to remain at thebase of the impeller blades since it has a much lower density. The main portion of liquid and possibly some vapor, depending on the mix,is discharged through the outlet port. A small portion of the liquid flow follows the mini-channel and eventually is forced into the areabetween the impeller blades. The remaining vapor which was not drawn through the outlet port resides at the base of the impeller blades. Atthe end of the mini-channel, as the liquid is forced into the area between the blades, the area between and around the impeller blade isreduced. The liquid between the blades displaces and thus compresses the remaining vapor at the base of the impeller blades. The compressedvapor is then forced through the secondary discharge port where it combines with the liquid discharged through the outlet port as it is pulledinto the next stage or discharged from the pump. Thus entrained vapor is moved through each stage of the pump.
Each subsequent stage operates under the same principle. The number of stages can be varied to meet the required discharge head. Whenmultiple stages are required, the relative positions of the stage outlet ports are radially staggered to balance shaft loads.

LPG Side Channel Pumps
The SC58 model with direct-coupled drive is commonlyused in carousel cylinder filling plants.
General InformationHistory
The Side Channel pump was introduced into the Corken pump line in1996. This versatile pump is also used widely in industrial applications.Several features characterize this unique pump. First of all it can handleup to 50% entrained vapor which makes it ideal for pumping liquefiedgasses such as propane. It also has a special suction impeller that enablesit to operate under poor suction conditions as is often seen in undergroundtanks or other types of unloading situations. Additionally it is a multistageregenerative turbine type which allows it to pump against the high headpressures of carousel bottle filling and other applications.
Maintaining the Corken way of building a pump, the impellers float.This feature along with heavy duty bearings and optional cooling waterjackets allow this pump to operate in difficult applications with reliabilityand longevity. Versatility is also a key to Corken pumps and this one isdesigned for use both domestically and overseas with ANSI compatibleor DIN flange options, and multiple material and sealing arrangementsincluding seal-less magnetic drive models.
The side channel pump is designed for relatively low flow, high head,thin liquid and liquefied gas transfer. The most common uses for theLPG/NH
3 versions of the pump are shown at the right. More information
on other applications is available in our Industrial Pumps Sales Catalog.
Primary Applications
Propane bulk transfer
Propane cylinder filling
