Piston Diaphragm Pumps

The product range consists of a variety of heavy-duty hydraulically and mechanically driven piston and membrane pumps that cover a wide range of demanding solids transfer and process applications.

Serving some of the most sever roles in industries such as Mining, Wastewater, Power, Oil and gas, Food, Chemical, Cement, Marine, Ceramics and Corrugated Media industries, these pump helps you to work with difficult media in extreme conditions. Suitable for difficult sludges, slurries, solids and a variety of aggressive, abrasive and viscous fluids.

  • Solids Handling Pumps for difficult media at high pressure.
    ABEL SH SOLIDS HANDLING PUMPS span a wide performance range and are suited for a large number of pumping media and applications. These high pressure pumps really prove their worth when extremely abrasive, paste-like and compact media (e.g. dewatered sewage sludge) or mine tailings with high solids content have to be conveyed safely at high pressure. This pump has extra wall thickness and a large intake valve, which, when combined with a very good filling ratio, produce a service life that is longer than the norm. Along with the actual pump unit (consisting of sludge, hydraulic main and valve cylinders) an ABEL SH solids handling pump comprises a total of four components: the actual pump, the hydraulic drive unit, a screw feeder for sticky media to fill the product cylinder, and a control cabinet with PLC. The programmable logic controller is the “brain” of the system and allows for integration with complex processes and control room systems.
    • Duplex piston pump with hydraulically-actuated cone valves – short-circuit free, even at high pressures
    • Cone valves with elongated valve rods – safe protection against cross-contamination of the hydraulic circuit with the pumped media
    • Electrical pump control as standard with modern PLC for local or external parameters, e.g. incinerator temperature control
    • Capable of running dry
    • Enclosed pipeline transfer
    Fully automatic, efficient disposal and feed operations.
  • The efficient, solid purchase.
    The HP series offers a triplex plunger pump for high pressure cleaning with up to 16.0 MPa (2,300 psi). This series has proven its worth many times over, especially when used to clean filter cloths for chamber and diaphragm filter presses. Especially in process technology, ABEL HPT high pressure plunger pumps show a technological edge when used rigorously over a longer period of time. And that applies for quite varied media, such as salt water and salt solutions, acids, margarine, chemicals, and even lightly contaminated fluids. Built in mobile turnkey containers, HPT series pumps can be used in a number of applications, especially when you require a high degree of mobility because you need to keep changing locations.
  • Diaphragm pumps for difficult media.
    THE ABEL HMT is a single-acting, slow-running, dry-run secure triplex piston diaphragm pump. Very high operating pressures in connection with increased flow rates create special environments for pump specifications. When abrasive materials with an increased percent solids content are present, many industrial partners decide on an ABEL HMT. The HMT Pumps are also equipped with pre-formed diaphragms to the same specifications as the whole ABEL HM range. The superb resistance qualities of the special diaphragms are constantly demonstrated throughout the whole pumping process as there is no evidence of stretching or shrinking. The pumps in the HMT range are equipped with API cone valves and are also available for reverse-flow for nonstable sedimentary slurries.
    • The ABEL HMT-range is designed with a Triplex-Transmission gear with a 120° crank displacement which enables an optimal, even volume flow
    • This simple operating, slow-running Triple Piston Diaphragm Pump operates safely, even when dry
    • Able to demonstrate a performance with reduced pulsation and ease of operation, despite the increased operating pressures of up to 25.0 MPa.
    • Provides a clever solution to pumping suspensions that have high dry substance content and a high specific weight
  • Efficient handling of high flow rates.
    THE ABEL HMQ is a quadruple acting piston diaphragm pump that is primarily used for high flow applications. 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 slurries with a high, mineral based content have 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 control valve installed on the hydraulic side of the unit monitors not only the front diaphragm position, 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. As with the whole HM series, the HMT and HMQ pumps also make use of the advantages of modern diaphragm technology: Pre-formed, pressure balanced diaphragms which are adapted to the particular application and hermetically separated hydraulic and product sides. Equipped with an integral reduction gear and can be fitted 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.
  • Reliable under high pressures and flow rates.
    The ABEL HM piston diaphragm (membrane) pump range has been specially developed for operations with increased flow rates combined with high operating pressures. The ABEL HM is available in single or double-acting design. In addition to the attributes of piston diaphragm pumps such as self-priming and dry running resistance, the pumps are characterized by very low power consumption, quiet running and high reliability. The ABEL HM pumps are equipped with pre-formed diaphragms which remain stable throughout the duration of the pumping operations. The ABEL HM construction method has been tested in many various industries, as well as with very difficult media, and has proven to be operationally secure as well as providing a very high diaphragm and service life time.

    This robust pump technology is especially advantageous for many applications that require low pressure. The ABEL EM is a mechanically driven diaphragm pump that is highly energy efficient, because the drive does not require expensive compressed air. Its compact, special design does not require hydraulic fluid, and it can be suitably equipped to provide the performance required by each specific application. The patented Electric Diaphragm Pump is recognised as the world market leader in its class. The use of conventional pumps in a range up to 115 PSI often incurs high operating costs. Purchase cost is only a fraction of the total life cycle cost of a pump.

    ABEL CM piston membrane pumps are single or double action specialized pumps that are used for difficult media. They are highly resistant to wear, even when used at high pressures over an extended period of time. Their true double-membrane technology offers a high degree of safety. ABEL CM piston membrane pumps enable the transfer of highly abrasive, even grainy suspensions by using high-strength special membranes and ball valves, which prevent the medium being pumped from coming into contact with the piston and other mechanical control elements of the pump.
