Product Overview
The CHDF horizontal multistage stainless steel pump is equipped with a horizontal extended-shaft motor, featuring axial suction and radial discharge. All wetted components are made of high-quality stainless-steel plates formed by stamping and welding, allowing the pump to handle slightly corrosive liquids. It adopts advanced hydraulic models and precision manufacturing techniques, offering wide application, high efficiency, energy saving, and reliable quality. The pump is designed for industrial and domestic clean water supply systems.
CHDF Series Type Designation
Applications
The CHDF stainless-steel horizontal multistage clean water pump is suitable for both industrial and domestic water systems, including:
– Air-conditioning systems
– Fertilizing and metering systems
– Cooling systems
– Environmental protection applications
– Industrial cleaning
– Water supply and pressure boosting systems
– Water purification and treatment
– Domestic water supply
– Aquaculture and irrigation
– Other specialized uses
Operating Conditions
● Liquid temperature: -15°C to +70°C (standard type), +70°C to +110°C (hot water type)
● Ambient temperature: up to +40°C
● Maximum operating pressure: 10 bar
● Maximum inlet pressure is limited by total operating pressure
● Suitable for thin, clean, non-flammable, and non-explosive liquids without solid particles or fibers
● Can convey mineral water, softened water, pure water, light oil, and low-viscosity chemical liquids
● For liquids with density or viscosity greater than water, a higher-power motor should be used
● The suitability of the pump for a specific liquid depends on chlorine content, pH, temperature, and solvent composition

Installation Dimensions
(Installation data table)
Refer to detailed dimensional data provided in the table for each model, including motor type, overall length, height, and weight. Flange connections conform to international standards for easy maintenance and replacement.
Maintenance and Service
1. The inlet pipeline must be airtight without leakage of water or air.
2. Avoid long-term cavitation operation.
3. Do not allow the pump to operate beyond rated flow for extended periods.
4. Regularly monitor motor current to ensure operation within design range.
5. Lubricate bearings after every 500 hours of operation.
6. After long-term use, inspect for mechanical wear, noise, and vibration; replace bearings or seals as necessary.
7. Overhaul interval: approximately one year under normal operation.
Troubleshooting
Problem: Pump not discharging water
Cause: Inlet valve closed, suction blocked, or motor rotating incorrectly.
Solution: Open valves, remove blockage, and verify rotation direction.
Problem: Insufficient flow
Cause: Blocked pipeline or impeller wear.
Solution: Clean and inspect impeller, remove deposits, adjust valve opening.
Problem: Excessive noise or vibration
Cause: Loose mounting or bearing failure.
Solution: Tighten fasteners and replace bearings.
Problem: Overheating motor
Cause: Overload, friction, or low voltage.
Solution: Adjust flow, check bearings, and stabilize voltage.
Problem: Leakage
Cause: Worn mechanical seal or loose bolts.
Solution: Replace seals and retighten bolts.
