Reciprocating pump PMF / GMF This is a multi-line reciprocating pump for many applications - Subject to modifications - Being a universal type, our reciprocating pump is capable of meeting any challenge. The reciprocating pump can be fitted with various drives. Direction of rotation is as needed. Based on our long- standing experience, we can determine the appropriate type for every application. Reciprocating pumps can be used with oil and grease. General description: The reciprocating pump is capable of accommodating up to pump elements. Delivery volume per element each is 0,08 or 0, cm³/stroke at maximum and can be regulated continuously. Maximum operating pressure amounts to 0 bar. The reservoirs are made of steel sheet or transparent polyester material providing capacities between and 0 litres. The reservoir content can be monitored electrically.

- Subject to modifications - Mode of operation: The reciprocating pump is composed of the following main parts: The pump casing, the pump elements 9, the inner and outer drives 7, 8, and the reservoir. From the outer drive, the pump shaft is driven via a worm gear 7, 8. With this pump shaft, a pressure ring 6 runs around eccentrically, into which the pump elements 9 are hooked. Due to the eccentricity of pressure ring 6 to the pump shaft, every delivery piston will inevitably make a steady pressure and suction stroke with every turn of pump shaft. For pump elements description, see: pump elements mode of operation, please. Pump shaft is connected with a stirring mechanism that presses the lubricant to the intake holes of the pump elements 9 and cuts air bubbles up. In the level monitor fitted version, a follow-up piston for grease usage is provided for. This piston rests on the grease surface, thus enabling precise level monitoring. If there is no level monitoring provided for, a stripper is installed. 6 9 7 8 PMF pump elements assembly: When fitting another pump element into the reciprocating pump, please proceed as shown in the sketch beside: With the delivery piston being approximately pulled out half, insert the pump element diagonally upward into the casing's reception hole. Insertion and operation will be easier when the hole that serves to accommodate the delivery piston is filled with grease. Do not put the pump element into horizontal position and screw in, unless the delivery piston's head touches the pressure ring and ratches into the latter's groove. When demounting, pull the pump element cautiously out of the casing such that the delivery piston will remain within the pump element. Notes to operation: Reciprocating pumps must be operated with clean oil or grease from original drums only. If, upon start-up, filling is not made via the filling nipple, the pump, in case of initial filling, has to be filled with gear oil up to the stirrer wing's level. This way, proper deaeration is ensured. The lubricant leads must be cleaned and have no obstructions. They shall not be con-nected with the lubrication points, unless lubricant comes out free of bubbles. All delivery pipe connections should be checked for leakage. Page of 0
7 R Suction stroke Delivery volume - Subject to modifications - Pressure stroke 6 Pump elements mode of operation: Suction stroke is accomplished by delivery piston and control piston. In this process, delivery piston is actuated by the eccentric shaft, whilst the spring actuates control piston. The control piston closes pressure hole and is kept in a certain position as determined by the preset delivery volume. The delivery piston moves on, causing a vacuum to be built up in the proportioning space. When the delivery piston has opened suction hole, lubricant starts to be sucked from the reservoir. In case of pressure stroke, delivery piston moves to the left. In this motion, suction hole is closed and control piston displaced by virtue of the lubricant being available in between the delivery and control pistons until it releases pressure hole and the lubricant is delivered through the delivery piston to the outlet. The pump elements are delivered with maximum delivery volume, i.e. they are set to full stroke. The delivery volume can be adjusted continuously between and 00% of the nominal delivery volume. After having removed lock screw 7, the stroke is to be changed by means of the enclosed spanner through adjustment nipple 6. When turning the nippe to the right, delivery volume will decrease. At the adjustment nipple, there is a hexagon against which a spring loaded piston is pressing radially. Thus, any independent change of the delivery volume will be prevented. At the same time, the latching serves as a measure for setting the delivery volume. Six latches equal one rotation of the adjustment nipple and a reduction of the nominal delivery volume by %. latches (minimum) equal a delivery volume reduction down to % of the nominal delivery volume. The element having a piston diameter of 8 mm = 0, cm³/stroke is marked with a red ring "R". Page of 0
