Product Description

GDJM Mechanical Diaphragm Metering Pump

Product Description

GDJM Mechanical Diaphragm Metering Pump
The metering pump is a special reciprocating displacement pump, of which the discharge can be infinitely regulated between 0 and 100% to feed corrosive and non-corrosive liquid at a certain amount for different process flows. It includes piston metering pump, hydraulic diaphragm metering pump, and mechanical diaphragm metering pump. The products comply with GB/T7782-1996 metering pump standards. 
GDJM series mechanical diaphragm metering pumps are extensively used in petroleum, chemical, water treatment, environmental protection, food, light industry, paper-making, pharmacy, dyeing and finishing, metallurgy, and mining.
 

Major parameters
1. Rated discharge 4~1800L/h,Max.rated pressure 0.8MPa.
2. Temperature of medium discharged -30~50ºC(100ºC for stainless steel).
3. Dielectric viscosity: 0.3~800mm²/S.
4. Metering accuracy ±2%.
