Brief insight into the functioning of an HMQ diaphragm pump

13th November 2017


The HMQ (Hydraulic Membrane (diaphragm) pump Quadruplex) is a quadruple-acting piston membrane pump. When they move in either of two directions, the delivery pistons activate, by means of two cylinders, the four product diaphragms in the radial direction with respect to the pistons. The power transmission is ensured by the hydraulic fluid. The (equal) linear deflection of the diaphragms is ensured by a mechanical diaphragm position control. The product valves are opened accordingly to the suction stroke or the discharge stroke of the diaphragm; at each product side, there is one suction valve and one discharge valve. For a low pulsation operation, ABEL provides a special pulsation dampener which is also equipped with an automatic regulation system.

The HMQ is powered electrically and, when a frequency converter is used, it is perfectly suitable for pumping at very different flow rates (generally at 10-100% of the specified flow rate). The customer can adapt the speed to its specific application at any time. Intermediate gearboxes or belt / pulley systems, in case of a lower power transmission, are used as a gear reduction between drive motor and HMQ gear. The rotary movement of the drive shaft is transferred to the eccentric and by means of eccentric rods and cross-heads it is converted into a stroke movement of the piston rods.

Abel worked very hard to make the success story of this HMQ pump hit a new milestone, the 100th pump of this product series was shipped to India.
