Model: JSD series plunger metering pump

Flow range: 23-3000L/H

Maximum pressure: 50Mpa

Material: plunger - ceramic, valve ball - ceramic/SUS stainless steel

Pump head material: 304, 316 (options: duplex steel, Alloy C-276, 904, titanium, PVDF, zirconium, etc.)

Motor: 380V, 3PH, 50HZ (options: 110-480V, single-phase, 60HZ, variable frequency/explosion-proof/explosion-proof variable frequency, etc.)

Technical characteristics of plunger metering pump

• The diameter of the plunger can be made very small, usually D6-200mm.

• The plunger pump has a wide range of discharge pressures and should be made into a high-pressure pump.

• Within the range of 10% to 100% flow rate, the measurement accuracy can reach ± 1%, and the maximum pressure can reach 50MPa.

• The plunger metering pump can adjust the flow rate by adjusting the stroke length, and is equipped with a variable frequency motor. The frequency converter can change the motor frequency to control the flow rate, and remote control can be achieved; Can be equipped with a digital controller for metering pumps, achieving digitization and local and remote control.

• It can be made into various types of insulation pump heads (including steam, hot water, electric and other heating pump heads), and can be made into multiple parallel units for adding different liquids, flow rates and pressures.

• Simple structure, easy maintenance, and good cost-effectiveness.

• Can transport high viscosity media, not suitable for transporting corrosive slurries and hazardous chemicals.

• The shaft seal is a packing seal with leakage, and the pre tightening force of the packing needs to be adjusted periodically. The packing and plunger are a pair of vulnerable parts.

• There is no safety relief device, it is recommended to install a safety valve on the outlet pipeline of the pump.

Advantages of high power plunger metering pump

plug

Adopting ceramic plunger or ceramic spray plunger, it has strong corrosion resistance and is suitable for various harsh working conditions. It has high surface smoothness, high hardness, and a long service life that is more than three times that of general polishing, electroplating and other process plungers.

filler

Patent packing sealing component, simple structure, compressible self-locking, high operating pressure. Using PTFE based material, it has good corrosion resistance and self-lubricating performance. Combined with the company's standard ceramic plunger, it has a long service life.

Unique metering pump crankshaft adjustment mechanism [Invention patent number: ZL.9】

This patent is a metering pump stroke arbitrary adjustment mechanism with a high load-bearing integral structure. Compared with the traditional N-crankshaft, inclined groove flat shaft, camshaft, and parabolic turntable structure, the main transmission shaft and adjustment mechanism adopt a complete machine design, with more parallel transmission and higher concentricity of the adjustment mechanism. They have the characteristics of high load capacity, high repeatability accuracy, etc. The main transmission shaft structure is precise and compact, with higher transmission efficiency and certain cost, energy saving, and economic benefits.
