Based on the performance parameters of IS-type and IR-type centrifugal pumps, Shengshi Datang has developed the ISW, ISWR, ISWH, ISWY, ISWHY, ISWD, ISWRD, ISWHD, ISWYD, and ISWHYD series horizontal centrifugal pumps in compliance with ISO 2858 standards. This series adopts advanced domestic hydraulic models and optimized designs, making it an ideal new generation of high-efficiency and energy-saving horizontal centrifugal pumps.
Operating Conditions
The maximum working pressure of the pump system is 1.6 MPa, meaning the sum of the pump’s suction pressure and head must be less than 1.6 MPa. (If the system pressure exceeds 1.6 MPa, please specify during ordering so that cast steel can be used for the pump's flow-passing and connection components.) The pump is designed to handle clean water or other liquids with similar physical and chemical properties. (If the medium contains fine particles, please specify during ordering to equip wear-resistant mechanical seals.) Ambient temperature should not exceed 40°C, altitude should not exceed 1000 m, and relative humidity should not exceed 95%.
Product Features
1. Compact Structure:
This single stage horizontal end suction centrifugal pump features an integrated pump-and-motor design, offering an attractive appearance and a footprint approximately 30% smaller than conventional horizontal pumps. Equipped with an IP54-rated outdoor motor, it can be installed directly outdoors without a pump house.
2. Smooth & Quiet Operation:
High concentricity ensures stable performance. The direct motor-to-pump coupling minimizes vibration and noise, while the dynamically balanced impeller extends bearing life and improves the operating environment.
3. Premium Mechanical Seal:
Hard-alloy mechanical seals enhance wear resistance, ensure leak-free operation, and prolong service life.
4. Advanced Hydraulic Design:
The innovative impeller design delivers high efficiency and superior performance.
5. Unique Structural Details:
A drainage hole at the pump base and pressure taps on the inlet and outlet flanges facilitate maintenance and monitoring.
6. Pipe-Friendly Configuration:
With a horizontal inlet and vertical outlet, pipeline layout and installation are simplified.
Main Applications
1. ISW Horizontal Clear Water Pump:
Designed for conveying clean water and other liquids with similar physical/chemical properties. Suitable for industrial/urban water supply/drainage, high-rise building pressurization, garden irrigation, firefighting boost, long-distance transport, HVAC circulation, bathroom hot/cold water circulation, and equipment matching. Operating temperature: T ≤ 80°C.
2. ISWR/ISWRD Horizontal Hot Water Pump:
Widely used for hot water circulation and pressurization in boilers (energy, metallurgy, chemical, textile, papermaking industries, hotels, baths, etc.) and urban heating systems. Operating temperature: T ≤ 120°C.
3. ISWH Horizontal Chemical Pump:
Transfers non-solid, corrosive, water-like viscosity liquids. Ideal for petroleum, chemical, metallurgy, power, papermaking, food/pharmaceutical, and synthetic fiber industries. Operating temperature: -20°C ~ +120°C.
4. ISWB Horizontal Pipeline Oil Pump:
Transports gasoline, kerosene, diesel, and other flammable/explosive liquids. Operating temperature: +20°C ~ +120°C.

The unit consists of three parts: pump, motor, and base. The pump structure comprises the pump body, impeller, pump cover, mechanical seal, and other components. It is a single-stage, single-suction, horizontal centrifugal pump, with the pump body and cover split at the impeller’s rear (rear-halved design).
Most pumps feature seal rings on both front and rear sides of the impeller, along with balance holes on the rear cover to counteract axial thrust on the rotor.
a.Flow Design: Axial horizontal inlet, vertical upward outlet.
b.Shaft Configuration: Pump and motor are co-axial. The motor shaft extension uses double angular contact ball bearings to partially balance residual axial force.
c.Installation: Direct-coupled with no alignment required; shared base with IG-type vibration isolators for reduced vibration.
Anti-corrosion chemical process centrifugal pump is a type of pump used in the chemical industry for transferring, discharging, feeding, and lubricating various chemicals. It operates on the principle of centrifugal force, where the rotation of the impeller throws the liquid outward, creating a pressure difference that allows the liquid to flow from the inlet to the outlet.
THF fluoroplastic fluorine lined chemical centrifugal pump is a fluorine lining for excellent corrosion resistance. High - quality materials ensure durability. Efficient centrifugal action enables stable fluid transportation, suitable for various chemical processes.
Full plastic anti-corrosion abrasion resistance electric centrifugal pump —— it uses high - quality plastics for parts like the impeller and shell. This pump has excellent wear resistance, able to handle media with solid particles. It shows great corrosion - resistance to various chemicals. With a well - designed impeller, it operates efficiently with low noise and vibration, suitable for multiple industries.
