Model specification description

SJM series mechanical diaphragm metering pump

A metering pump is a reciprocating special volumetric pump that can continuously adjust the flow rate within the range of 0-100% according to the needs of various process flows, and can quantitatively transport corrosive and non corrosive liquids without solid particles. It is divided into plunger metering pump, hydraulic diaphragm metering pump, and mechanical diaphragm metering pump. The product complies with the GB/T7782-2008 metering pump standard.

The SJM series mechanical diaphragm metering pump products are widely used in industries such as petroleum, chemical, water treatment, environmental protection, food, light industry, papermaking, pharmaceuticals, printing and dyeing, metallurgy, and mining.

characteristic

◆Economical pump with optimal cost-effectiveness.

◆ The structure is simple and easy to maintain.

◆ Eccentric cam mechanism drive, compact mechanism, small equipment installation space.

◆ Oil immersed lubrication only requires regular replacement of lubricating oil, and the lubrication system does not require specialized maintenance. Double convex wheel ball bearings drive and work smoothly.

◆ The flow rate can be adjusted in both running and stopping states of the pump.

◆ The new type of PTFE rubber composite diaphragm is corrosion-resistant, has a long service life, and is suitable for transporting various corrosive and hazardous liquids.

◆ Multiple optional overcurrent materials are available, and other special materials can be customized according to usage requirements to be suitable for transporting various corrosive and non corrosive liquids.

Note: Standard overcurrent material I

◆ Completely leak free, high safety, capable of transporting various flammable, explosive, highly toxic, radioactive, strongly irritating, and highly corrosive liquids.

◆ The high-precision one-way check valve structure has many advantages such as precise measurement, compact structure, good sealing, long service life, strong interchangeability, low cost, and easy installation.
