ABEL RECIPROCATING POSITIVE DISPLACEMENT PUMPS
HMQ QUADRUPLEX PISTON
Efficient handling of high flow rates
The ABEL HMQ Quadruplex are easily identifiable due to their unique compactness and space-saving design. They come to the fore when large volumes of abrasive materials need to be transferred under high-pressure conditions. This also applies when slurry with a high, mineral based content has to be transferred, in such environments as the mining and/or cement industry.
The four, pre-formed diaphragms remain stable throughout the duration of the pumping operations. A regulating-valve installed on the hydraulic side of the unit monitors not only the front diaphragm, but also the rear diaphragm position. This concept of diaphragm monitoring, which provides a long service life standard, is one of the basic reasons behind the reliability and durability of these products.
Every ABEL HMQ pump is equipped with an integral reduction gear and can be fitted out with ball and/or API cone valves. The parts of the pump which will come into contact with the materials to be pumped are made of nodular cast iron (also rubber-coated), cast steel or stainless steel. A reverse flow design is also available for installation in cases of slurries which contain non-stable sedimentation.
The impressive service life and reliability of the ABEL HMQ has been clearly demonstrated in many world-wide applications. The initial, higher investment costs of an ABEL HMQ piston diaphragm pump, in comparison to other types of pumping systems, are quickly recovered through reduced energy costs, increased operating time and low maintenance costs.
