Model: JYSZ series hydraulic diaphragm metering pump

Flow range: 10-400L/H

Maximum pressure: 20Mpa

Membrane material: PTFE

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 hydraulic diaphragm metering pump

• No dynamic seal, no leakage, easy maintenance.

• The working pressure can reach 30MPa, and the measurement accuracy can reach ± 1%.

• The measurement accuracy is better than that of mechanical diaphragm pumps, and the sealing performance is better than that of plunger pumps.

• The flow rate control is achieved by adjusting the stroke length and variable frequency drive speed, and can be remotely and automatically controlled.

• The operating temperature of the medium should not exceed 100 ℃ and should not be lower than -20 ℃, otherwise it will affect the service life of the diaphragm.

• The application of advanced overload, limit, and oil replenishment three valve mechanisms not only ensures the satisfaction of hydraulic oil in the hydraulic chamber, but also avoids excessive oil replenishment, prevents hydraulic shock, and balances the forces on both sides of the diaphragm, improving the service life of the diaphragm. The diaphragm life can be increased to over 8000 hours.

• When transporting special media, a double diaphragm with a diaphragm rupture alarm device can be used to prevent accidents caused by the mixing of media and hydraulic oil when the diaphragm ruptures;

• Can be equipped with a digital controller for metering pumps, achieving digitization and local and remote control.

Advantages of High Strength Hydraulic Diaphragm Measurement

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.
