JWM-B series mechanical diaphragm metering pumps

It is suitable for environmental protection, water treatment, pharmaceutical, papermaking, new materials and other industries, sexual slurry and hazardous chemicals.

A metering pump is also known as a quantitative pump or a proportional pump. A metering pump is a special volumetric pump that can meet various strict process requirements, with a flow rate that can be infinitely adjusted within the range of 0-100%, and is used to transport liquids (especially corrosive liquids).
A metering pump is a type of fluid conveying machinery, characterized by its ability to maintain a constant flow rate independent of discharge pressure. The use of a metering pump can simultaneously perform the functions of conveying, metering, and regulating, thereby simplifying the production process. By using multiple metering pumps, several media can be accurately proportioned and mixed into the process flow. Due to its outstanding performance, metering pumps are now widely used in various industrial fields such as petrochemicals, pharmaceuticals, and food.

Product Description

Product Overview

The mechanical diaphragm metering pump is a diaphragm pump that relies on mechanical direct drive for the deflection and deformation of the diaphragm.
Mechanical diaphragm metering pumps are generally suitable for conveying liquids without solid particles with a temperature of -15°C~85°C and a viscosity of 0.3mm²/s~2000mm²/s. The flow rate can be continuously adjusted in the range of 0-100%, and the product has no leakage, simple structure, low maintenance cost, and good cost performance. The products are suitable for environmental protection, water treatment, pharmaceutical, papermaking, new materials and other industries, sexual slurry and hazardous chemicals.

function

1. The flow control mode of the pump has manual control and automatic control. Automatic control can be achieved by frequency conversion, and can also be achieved by adding a digital controller or stroke controller for the metering pump.
2. Parameter range: flow rate is 0.47~6000L/h, maximum working pressure 1.2MPa optional; The flow stability accuracy can be controlled at 1%.
3. Suction capacity: ≤3m (water column)
4. The product does not have a safety discharge device, and when the system is formed, the outlet pipeline of the pump needs to consider the installation of safety valves to improve the safety of operation.
5. Conveying flammable, explosive, highly corrosive, toxic and other dangerous chemicals, in order to prevent accidents caused by diaphragm rupture, the hydraulic end structure of double diaphragm with diaphragm rupture alarm device can be selected.

Fluid end overflow parts

According to the characteristics of the conveyed agent, the flow parts at the fluid end must meet the requirements for corrosion resistance.
Materials available: PVC, PVDF, PTFE, SS304, SS316L and other alloys (such as: alloy 20, 904L, titanium, Hastelloy, etc.).
Diaphragm material: PTFE or rubber composite PTFE.

Features introduced

1. Reinforced PTFE+ rubber multi-layer composite diaphragm, no leakage at all, more assured to use.

2.The pump head can be made of PVDF/RPP/PVC/SUS304/SUS316 for a wider range of applications.

3. It can be equipped with a digital controller to achieve remote control.

4. Precise adjustment of 0-100% flow rate can be carried out when running or stopping the pump.

5. The pump body is made of high-quality aluminum alloy die-casting, which is light in weight. The motor can be matched with single-phase and three-phase, which is convenient for power supply matching in different occasions.
