Product Description
Our technical team newly develops this diesel-driven double-suction split case pump with innovative structure.
It is developed on the basis of mature similar pump products.It adopts horizontal single-stage horizontal split case design.
It transports clean water and liquids with similar physical and chemical properties.Max allowable medium temperature: 80°C.
Wide application scenarios: process water supply, fire protection, urban flood control and drainage.
I. Model Description
Example: 500 S 35A;
- 500 -- Inlet diameter of the pump, 500 mm
- S -- Single-stage double-suction split case centrifugal pump
- 35 -- Design head, 35 m
- A -- First impeller trimming
II. Transmission Mode
Two optional drive types: direct drive, variable speed drive.
Matters to confirm before order: motor model, power, rotating speed.
We will match corresponding coupling or pulley specifications according to your parameters.
III. Rotation Direction
Viewed from the drive end, the pump rotates counterclockwise.
IV. Material Description
Optional manufacturing materials:
Copper, cast iron, ductile iron, 304 stainless steel, 316 stainless steel, 416 stainless steel, duplex steel, Hastelloy, Monel, titanium alloy, Alloy 20, etc.
V. Operating Conditions
1. Ambient temperature ≤ 50°C
Conveyed medium temperature ≤ 80°C
2. Medium pH range for cast iron pumps: 6–9
3. Max medium density: 1240 kg/m³
4. Suction parameters with foot valve and priming water
Max suction lift ≤ 6 m
Max suction pipeline length ≤ 10 m
VI. Performance Features
1. Nozzle layout
Suction and discharge nozzles are below pump shaft.Horizontal layout, perpendicular to shaft axis.
No pipeline disassembly or motor removal required for maintenance.Standard rotation: counterclockwise; customized rotation is acceptable.
2. Main components
Pump body, pump cover, impeller, pump shaft, double-suction wear ring, shaft sleeve
- Pump shaft material: carbon steel
- Other parts: cast iron, cast steel, stainless steel
3. Pump body & pump cover
Form the working chamber for impeller running.Inlet and outlet flanges reserve tapped holes for vacuum gauges and pressure gauges.
Threaded drain holes are set at the bottom of flanges.
4. Impeller
Passes static balance test.Fixed on pump shaft with sleeve nuts.
Axial position can be adjusted freely.Symmetrical double-suction design automatically balances axial thrust.
5. Bearing assembly
Radial bearings installed in two-end bearing housings.
Support stable pump operation.Grease lubrication as standard.
6. Double-suction wear ring
Cut liquid back leakage from pressure chamber to suction chamber.
7. Driving options
Standard drive: motor connected by coupling
Optional drive: internal combustion engine / diesel drive
8. Shaft seal
Standard seal: gland packing
Optional seal: mechanical seal
Built-in packing ring stops air entering the cavity.Packing ring cools and lubricates seal chamber.
High-pressure liquid flows through trapezoidal groove on pump cover split surface to form water seal during operation.
