How to correctly choose the performance and price of the pump?

The correct choice of pumps requires comprehensive consideration of factors such as flow, head, material, efficiency, noise, brand, installation and maintenance, and budget. Before purchasing, you can first understand the performance and price of various pumps on the market, and make a wise choice after comparative analysis.

The type of pump generally uses a combination of letters and numbers, where letters indicate the type and purpose of the pump, and numbers indicate parameters such as flow, head, and caliber. For example, CPM130 represents an electric self-priming pump with a flow rate of 1.3 cubic meters per hour, a head of 35 meters, and an inlet and outlet diameter of 25mm. Common pump models include CPM, JET, IS, WQ, etc. Below Hunan Sanchang Pump Co., Ltd. to introduce some common parameters and its representation:

Flow (Q):The unit is cubic meters per hour (m3/h), which indicates the volume of liquid that the pump can deliver per hour.

Head (H):The unit is meters (m) and represents the difference in static head when the liquid is pumped.

Power (P):The unit is kilowatt (kW) and represents the motor output of the pump.

Import and export caliber (DN):Indicates the inlet and outlet caliber of the pump, in millimeters (mm).

Speed (n):The unit is revolutions per minute (r/min), which indicates the speed of the pump.

Efficiency (η):Indicates the working efficiency of the pump, usually expressed as a percentage (%).

Outlet pressure (P):The unit is Pascal (Pa) or megapascal (MPa), which indicates the outlet pressure of the pump.

When choosing a water pump, it is necessary to comprehensively consider various parameters and select the appropriate model according to the actual use. For example, for domestic tap water pressurization, self-priming pumps with small flow and low head are usually selected, while for industrial water treatment, centrifugal pumps with large flow and high head are usually selected.

Material:The material of the pump directly affects its service life and corrosion resistance. Common water pump materials are cast iron, stainless steel, copper, plastic and so on. Cast iron water pump is suitable for general water quality, stainless steel water pump is suitable for corrosive water quality, copper water pump is suitable for high purity water quality, plastic water pump is suitable for acid and alkaline water quality.

Budget:According to their own economic conditions, a reasonable budget to buy the cost of the pump. On the premise of meeting the needs of use, try to choose a cost-effective pump.

Noise:The water pump will produce noise during operation and affect the surrounding environment. Choosing a low-noise water pump can reduce noise pollution and improve the quality of life.

Brand and after-sales service:Choose a well-known brand of water pump, for example, Hunan Sanchang pump industry can guarantee product quality and after-sales service. Brand water pumps usually have high cost performance, long service life and low maintenance rate.

Installation and maintenance:Consider whether the installation and maintenance of the pump is convenient. For example, the vertical water pump has a small footprint and is easy to install. The submersible pump can be installed directly in the pool without additional pipe connections. In addition, choosing a water pump that is easy to maintain can reduce maintenance costs and time.
