■ Description

GDJM Mechanical diaphragm digital chemical dosing 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 a piston metering pump, hydraulic diaphragm metering pump, and mechanical diaphragm metering pump. The products comply with GB/T7782-1996 metering pump standards.

Major parameters of mechanical diaphragm digital chemical dosing metering pump:

1. Rated discharge 4~1800L/h, Max.rated pressure 0.8MPa.

2. Temperature of medium discharged -30~50℃(100℃ for stainless steel).

3. Dielectric viscosity: 0.3~800mm²/S.

4. Metering accuracy ±2%.

■ Application

GDJM Mechanical diaphragm digital chemical dosing metering pumps are extensively used in such industries and sectors as petroleum, chemical, water treatment, environmental protection, food, light industry, paper-making, pharmacy, dyeing and finishing, metallurgy and mining.

■ Features

1. Economical pump with the optimal cost-performance ratio.

2. Simple in construction and easy to repair.

3. Driven by eccentric cam gear, compact, and requiring small room for erection.

4. Dip-feed lubrication, requires periodic replacement of lubricating oil only. No special maintenance of the lubrication system is required. Pushed by double cam ball bearing, and in steady operation.

5. The discharge is adjustable whether the pump is in operation or not.

6. The new PTFE and rubber composite diaphragm is corrosion resistant, has a long service life, and is suitable for the discharge of various corrosive and hazardous liquids.

7. There are many optional overflowing materials. In addition, other special materials may be customized based on the operating requirements to make them suitable for the discharge of various corrosive and non-corrosive liquids.
