Fixed displacement pump

MCY-type fix displacement pump, its relatively simple principle, the fix displacement pump drive shaft and the cylinder connected with the spline to drive cylinder rotation, so evenly distributed in the cylinder plunger on the seven centers around the shaft rotation. End of each plunger has a slippery boots, centering spring ball through the inner sleeve, return, that will slide into the shoe down on a certain angle with the axis of the inclined disk. When the cylinder rotates, the plunger for reciprocating motion at the same time to complete the oil absorption and oil pressure moves. Centering spring through the coat with the oil pan on the cylinder pressure played a role in the initial seal. Slip boots and oil pan are used with a hydraulic static equilibrium, not only to reduce pump wear and tear, but also have a very high-pressure pump volumetric efficiency and mechanical efficiency.

This series of  fix displacement pump will have pressure 315bar pure hydraulic oil input to a variety of hydraulic machines, hydraulic system fluid motivation to generate a huge motivation. At the same time that the pump can be used as the use of hydraulic motors. According to the needs of a variety of variables in this form of pump. The oil pump, oil motors are widely used in shipping, aviation, mining, metallurgy, casting, forging, machine tools of various types of machinery, characterized by small size, high efficiency, long life, advanced design, compact structure and easy maintenance.

 We offer the serious of fix displacement pump as 2.5MCY14-1B\5MCY14-1B\10MCY14-1B\25MCY14-1B\40MCY14-1B\63MCY14-1B\80MCY14-1B\160MCY14-1B\250MCY14-1B
