LS submerged pump is a type of centrifugal pump that is designed to operate while fully submerged in the fluid being pumped. The pump is widely used in chemical processing, pharmaceutical, and other industries where fluids need to be transferred between tanks or other containers.
Classification
LS submerged pumps can be classified into three categories based on their construction materials:
Stainless Steel LS Submerged Pump
These pumps are made of stainless steel and are suitable for pumping a wide range of fluids including acids, alkalis, and solvents. They are widely used in the chemical and pharmaceutical industries.
FEP-lined LS Submerged Pump
These pumps have a fluorinated ethylene propylene (FEP) lining and are designed to handle highly corrosive fluids such as hydrochloric acid, sulfuric acid, and nitric acid.
PTFE-lined LS Submerged Pump
These pumps have a polytetrafluoroethylene (PTFE) lining and are suitable for pumping highly corrosive fluids at high temperatures.
Characteristics
High efficiency
LS submerged pumps are designed with high-efficiency impellers that help to reduce energy consumption and operating costs.
01
Corrosion resistance
The construction materials used in LS submerged pumps are highly resistant to corrosion, ensuring a long service life and low maintenance costs.
02
Submerged operation
LS submerged pumps are designed to operate while fully submerged in the fluid being pumped. This eliminates the need for a separate suction line and reduces the risk of cavitation.
03
Low noise
LS submerged pumps are designed to operate with low noise levels, making them ideal for use in noise-sensitive environments.
04
Easy maintenance
The design of LS submerged pumps makes them easy to maintain, with simple access to the impeller and other critical components.
05
In conclusion, LS submerged pumps are a reliable and efficient solution for fluid transfer in a variety of industries. With their corrosion resistance, high efficiency, and easy maintenance, these pumps offer a cost-effective and long-lasting solution for pumping corrosive fluids.
The structure and feature of the LS concentrated submerged sulfuric acid liquid pump
The LS submerged pump works as a vertical single-stage single-suction centrifugal pump mainly including pump body, pump cover, impeller, shaft, baseplate, intermediate nozzle, outlet pipe, sealing component, bearing, coupler and other parts.
Its axial thrust is mainly balanced by back blade of impeller.
The rest axial force and the rotor weight are borne by rolling bearing.
The pump can increase the insertion depth of both suction pipe and pump assembly by making full use of its own suction height.
However, before the pump's starting, the liquid level must be higher than the impeller center line.
Rotation direction: Taken from motor to pump end, the pump adopts a counterclockwise rotation mode.
