OVERVIEW

PRODUCT DESCRIPTION

Strong, compact design; no moving seal, no leakage, sealing performance is better than plunger pump.

The variable eccentric mechanism is adjusted to ensure that the flow pulsation changes smoothly, and the new type of adjusting mechanism makes the adjustment more accurate and reasonable.

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 belt splitting 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.

The motor controller controls the three-phase motor in the "on / stop" mode and adjusts the output flow.
