HMQ Piston Diaphragm Pumps

The pumps which are included in the ABEL range, HMQ (Quadruplex) are easily identifiable due to their unique compactness and space-saving designs. 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 which are incorporated in an ABEL HMQ 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 high 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. These multiple-application, piston diaphragm pumps are an ideal construction for transfer operations involving flows of up to 800 m³/h and pressures of up to 25.0 MPa, also providing economical advantages for the user.

The impressive service life and reliability of the ABEL-HMQ-Pumping concept 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, soon redeem themselves in a relatively short time. The main reasons for this amortization lie in the reduced energy costs, increased operating time and our experience based, knowledge of the reduced maintenance costs when compared to other types of pumping systems.
