■ Description

GDJ-M High pressure hydraulic diaphragm dosing metering pump is widely utilized across various industries including petroleum, chemical industry, spinning, food industry, papermaking, atomic energy, power plants, plastics, pharmacy, water works, environmental protection, and more.

1. It is equipped with an installed stroke adjustor and can be remotely controlled.

2. It is leakage-free, offers low noise, and is easy to operate and maintain.

3. It provides more precise measurement compared to mechanical diaphragm pumps and better sealing compared to plunger pumps.

4. It incorporates an advanced overload protection, limiting displacement, and a three-valve structure for adding oil. This not only ensures sufficient hydraulic oil in the hydraulic chamber but also prevents excess oil and hydraulic shock. This helps to achieve balance on both sides of the diaphragm and extends its service life.

5. The diaphragms are multi-layered. The first layer is made of super tough acid-resistant Teflon, the second layer is EPDM, the third layer is a 3.0mm SS304 support iron core, the fourth layer is reinforced nylon fiber, and the outermost layer is coated with EPDM gum elastic.

Major performance parameters of GDJ-M Hydraulic diaphragm dosing metering pump:

1. Single-joint maximum flow: 40000 L/h.

2. Maximum discharge pressure: 50 MPa.

3. Steady state accuracy: ±1%.

4. Media Viscosity: 0-800mm²/s.

5. Temperature of transporting media can reach over 450℃.

GDJ-M High pressure hydraulic diaphragm dosing metering pump accessories:

■ Application

GDJ-M High pressure hydraulic diaphragm dosing pump is suitable for handling various liquids, including clear water at normal temperature, highly corrosive, volatile, flammable, explosive, highly toxic, foul-smelling, highly corrosive, high-density, medium-viscosity, radioactive, or other precious liquids. It can also transport suspended liquids. To prevent accidents caused by the mixing of the medium and hydraulic oil after the diaphragm ruptures, as well as for handling flammable, explosive, highly toxic, and valuable liquids, a double diaphragm metering pump equipped with a diaphragm rupture alarm device can be selected.

GDJ-M Hydraulic diaphragm metering pump is suitable for various industries and applications, including petroleum, petrochemical and chemical processes that require high pressure and large flow rates, as well as land and offshore oil and gas skid-mounted systems for hazardous chemicals injection and delivery. It can also be used in nuclear power, military, and other special process applications, as well as in environmental protection, pharmaceutical, paper, food, and other key processes of the industry.

■ Features

Main features of GDJ-M High pressure hydraulic diaphragm dosing metering pump:

1. Each pump has with internal pressure relief valve protecting the pump from over-pressure conditions.

2. The flow rate can adjusted via a unique adjusting mechanism from 0-100%.

3. The adjustment can be carried out when the pump is in operation or at the stop.

4. The steady rate accuracy is ±1% from 30%-100% of the maximum output. High measurement accuracy.

5. Automatic operation is achieved by variable speed drive.

6. A double diaphragm with a diaphragm rupture detecting system is available to prevent accidents caused by a mixture of hydraulic oil and liquid after diaphragm ruptures.

7. Design and manufacturing standard GB/T7782-2008.

8. It can remove the gas remaining in the hydraulic oil and keep the hydraulic oil rigid.

9. Completely sealed and no leakage.

10. The control system of the diaphragm is in full rear position.

Details of GDJ-M High pressure hydraulic diaphragm dosing metering pump:

The first High-performance diaphragm pump:

1. Standard stainless steel liquid end: single head maximum flow rate 40,000 L/h, maximum pressure 50MPa.

2. Standard PVC liquid end: single head maximum flow rate 10,000 L/h, maximum pressure 10 bar.

3. Maximum flow rate of 10000 liters/hour in a single head, maximum pressure 10 bar.

4. Built-in combined safety valve to prevent excess pressure and automatic venting.

5. Measuring accuracy ± 1%.

6. Conveying medium temperature 100 ℃, special circumstances can reach 350 ℃.

7. Diaphragm PTFE, easy to install without leakage.

8. Using the latest technology, automatic control of oil replenishment, is safe and reliable.

9. Diaphragm pump (on-site/remote) rupture detection can choose pressure or electrolytic liquid type transmission end lubricant and hydraulic oil hydraulic end completely isolated low maintenance costs.

Hydraulic end:

1. A variety of standard hydraulic end forms including high-performance diaphragm pump heads, metal diaphragm pump head

2. Optional insulation jacket and other special hydraulic end forms

3. Diaphragm pumps can choose pressure or electrolyte type double diaphragm leakage detection (local/remote) alarm.

4. The pump head, check valve, diaphragm, plunger, packing, and other materials have special options.

5. High-precision inlet and outlet check valves with single ball valve, double ball valve, cone valve, and other optional configurations
