OVERVIEW

PRODUCT DESCRIPTION

Strong, compact design; immovable seal, sealing performance is better than plunger pump.

The variable eccentric mechanism is adjusted to ensure the smooth change of flow pulsation; the new regulating mechanism is more accurate and reasonable.

The measurement accuracy is high, and the steady-state accuracy can reach ±1%.

The built-in limit oil filling valve ensures the balance of hydraulic oil, and the built-in adjustable safety valve fully protects the hydraulic end parts to avoid diaphragm rupture and other parts damage caused by high pressure in the hydraulic cavity.

The double diaphragm rupture alarm device can be used when conveying corrosive slurry, flammable and explosive and other dangerous chemicals.

Power supply: 380V/220V-50Hz/60Hz/ three-phase / single-phase.

Frequency conversion controller, accept external control signal, adjust stroke speed, input signal: 4-20mA analog signal.

Motor control, "on / stop" mode to control the three-phase motor, adjust the output flow
