Stainless Centrifugal Pump

The CA horizontal stainless steel single-stage centrifugal pump features axial suction and radial exhaust. Its counter-axial design allows for easy removal of the motor and impeller without disassembling the pump casing and piping, facilitating maintenance.

The CA horizontal Stainless Centrifugal Pump is precision-cold-stamped from stainless steel sheet.

• Utilizes new hydraulic bulging technology for a secure structure.
• Voltage flow path design for high efficiency.
• Pump body, pump cover, impeller, and other flow-through components are made of SUS304.
• Elegant square motor design.
• Lightweight structure, mild corrosion resistance, and durability.
• Mechanical shaft seal for safety and leak resistance.
• Connection: Flange connection, installation dimensions comply with GB5662 & EN733 standards.

The CA Stainless Centrifugal Pump is a versatile product from Sihong, suitable for transporting a variety of media, including water and industrial liquids, across a wide range of flow rates and pressures.
Typical applications include:

• Water supply: water plant transportation, zoned water supply, and main pressure boosting
• Industrial pressure boosting: process water systems, cleaning systems, brewing and food industry systems
• Industrial liquid transportation: boiler feed water, cooling and air conditioning systems, condensate systems, and weak acid and weak base transportation
• Water treatment: raw water transportation, swimming pool systems
• Agricultural irrigation, healthcare, petrochemicals, aquaculture, and more.

• Clean, non-flammable, non-explosive liquids free of solid particles and fibers
• Liquids with a temperature between -20°C and +104°C
• Ambient temperature up to +50°C
• Installation altitude up to 1000 meters
• Maximum operating pressure 10 bar

   

• Equipped with a fully enclosed, air-cooled, 2-pole or 4-pole extended-shaft motor
• Protection Rating: IP55
• Insulation Class: F
• Power Supply (±10%): 1 x 220V/50Hz, 3 x 220V/380V/50Hz. Single-phase motors are available from 0.37 to 2.2kW. Includes a built-in thermal protector.

It is recommended to calculate the inlet pressure "H" in the following situations:

• High liquid temperature
• Flow rate significantly exceeding the rated flow rate
• Pumping from a low location
• Pumping from a long pipeline

Poor inlet conditions: To avoid cavitation, a minimum pressure must be maintained on the pump's inlet side.

The maximum suction head "H" in meters of head can be calculated using the following formula:

H = Pb x 10.2 - NPSH - Hf - Hv - HS

Pb = atmospheric pressure, in bar (atmospheric pressure is considered 1 bar). In closed systems, Pb represents the system pressure (in bar).

NPSH = Net Positive Suction Head, in meters (can be read from the pump's NPSH performance curve in the catalog).

Hf = Friction loss in the suction piping (in meters).

Hv = Vapor pressure (in meters), can be read from a vapor pressure gauge.

Hs = Safety margin, with a minimum of 0.5 meters.

If the calculated H value is positive, the pump can suction a head of "H" meters on the suction side. If it is negative, the inlet must have a head of at least positive "H" meters to prevent cavitation in the pump.

1. When installing piping, ensure that the pump casing is not subjected to external forces from the piping.
2. The Stainless Centrifugal Pump must not be installed with the motor below it.
3. The pump should be installed horizontally on a flat, solid foundation, with the pump's suction inlet facing horizontally and the discharge outlet facing vertically.
4. To facilitate inspection and maintenance and allow for air flow, allow at least 0.3m of clearance behind the motor.
5. The pump's inlet pipe diameter must not be smaller than the specified size.
6. The pump should be installed in a well-ventilated and frost-proof area.
7. If the pump is installed outdoors, it must be properly covered to prevent water from entering the electrical components.
8. The electrical wiring must protect the pump from damage caused by phase loss, leakage, voltage fluctuations, and overload.
9. To ensure optimal operation and minimize noise and vibration, vibration damping measures may be necessary in some applications.
