Function

Drive of central lubrication pump ZP4000 is effected by means of electromotor with step-down gearing flanged onto the housing and linked with the worm shaft via Woodruff key in form-fit connection. Each feed-line connection is equipped with a delivery piston and a control piston. A rotary motion is imparted on the pump shaft with cam disk via drive the delivery piston getting a stroke motion. The control gear is to actuate the control piston. Due to the stroke motion of delivery pistons, lubricant intake is effected through the control ducts of control pistons and delived into the pressure bore. The scraper plate is delivering the lubricant to the suction bores. The stirrer blade pressing the lubricant through the sieve plate into the suction compartment is arranged in the lubricant reservoir. The central lubrication pump ZP4000 can be supplied with 1 pumping unit with a maximum of 8 feed-line connections. Upon dispatch of pumps, the rate of delivery has been set to maximum value. The rate of delivery can be  et infinitely from 0 to 0.2 cm³. Feed-line connections not required shall be put to “zero rate of delivery” and should not be closed. There is a possibility of choose between sheet-metal and plastic lubricant reservoirs. The lubricant reservoirmade of plastics can be equipped upon request with electric filling-level control indicating the minimum filling level.
