Products Description

ES series double suction horizontal split case pump sre designed with double suctions.This kind of pumps are of high flow rate, high efficiency,stable operation,low noise and long serived life,easy to install and maintain.Widely used in plant,mine,city water supply,irrigation,HVAC and vessel industry.

Double suction design: The double suction impeller design allows liquid to enter the impeller from both sides at the same time, which can greatly reduce the axial thrust of the pump and improve the operating stability of the pump. The double suction design also enhances the flow capacity of the pump and can meet the needs of large projects for larger flows.
Split center structure: The pump casing is a horizontal split center structure, which is convenient for maintenance and repair. The pump casing can be opened horizontally along the axis, and key components in the pump (such as impellers, shafts, etc.) can be maintained and replaced without disassembling the pipeline. This design greatly reduces downtime and maintenance costs.
Strong adaptability: Double suction split center pumps can adapt to various working environments, can handle a variety of media such as clean water, seawater, oil, etc., and can operate stably under complex working conditions such as high temperature and high pressure. You can contact us before placing an order to select the appropriate model and product accessories according to the specific usage scenario.
Low noise and low vibration: The double suction horizontal split case pump has a stable structure and good dynamic balance. The double-suction split case pump generates low noise and vibration during operation, making it suitable for applications with strict requirements on environmental noise.

application

HVAC and cooling tower---Used in large buildings, such as commercial complexes, hospitals, and schools, to circulate chilled and hot water for heating and cooling.
Municipal water supply---Used in pumping stations for the supply of drinking water to cities and towns.
Pump station
Marine and slip building---Double suction horizontal split case pump manage water levels in ships. Their high flow capacity helps in efficiently pumping water in and out of the ballast tanks to adjust the ship's weight and stability.
Power plant/water plant
Industrial water supply system
Fire fighting system---Integral in high-capacity fire protection systems, especially in industrial facilities and large buildings where a robust water supply is necessary.
