The development of the E-Series was based on the extensive experiences with the proven pump models. The solid design with distinctive wall thicknesses, the flange connection capability, the ring tightening structure and more construction features are responsible to meet the customer demands of safety, quality and reliability. Six pump sizes available with optional equipments cover most applications in the market. Pulsation dampeners are available as screw-on and flanged models.
The Almatec® C-Series Air-Operated Double-Diaphragm (AODD) Pump is a cost-effective, reliable and superior-built alternative and features a solid design suitable for a wide array of pumping tasks.
The suction and discharge ports are available as separate housing parts. In addition to the standard connection, two further connection foot-prints are available to match existing installations. The ring tightening structure, good suction head, self-priming and dry run capability as well as the absence of drives, rotating parts and shaft seals are further features.
Almatec® CXM Series Air-Operated Double-Diaphragm (AODD) Pumps are general-purpose pumps designed for low- to medium-duty applications and to operate as drum pumps.
Thanks to the pump’s modular design, CXM Series is available with seven different product connections – four sizes with NPT connections and three sizes with BSP connections. The NPT pump sizes 10, 20, 50 and 130 can be changed by rotating the center block. The product connections of the BSP pumps sizes 25, 55 and 135 are located on the face side of the pump. This wide range of product connections allows a precise adjustment of the pump to the specific application.
When developing Almatec® CHEMICOR Series Stainless-Steel Air-Operated Double-Diaphragm (AODD) Pumps, special attention was paid to the shape of the product chambers. The result is a pump design that offers soft changes in direction, smooth flows and no dead corners. The pump image shows a model with optional draining system.
CHEMICOR Series pumps are manufactured from stainless steel 1.4408/SS316 (G-X 6 CrNiMo 18 10), which is a cast steel that is resistant to corrosion and acids, and is frequently used for fittings and pump casings because of its good general chemical stability. This material in a precision lost-wax casting is used for the wetted housing parts of the CHEMICOR Series. The lost-wax process is a complex casting process yielding a smooth and dense surface with increased resistance to corrosion.
Almatec® BIOCOR Series Air-Operated Double-Diaphragm (AODD) Pumps have been specifically designed for critical sterile applications within the pharmaceutical, biotech and food industries. BIOCOR Series pumps are EHEDG certified and conform to EC1935/2004, FDA, USP Class VI and ATEX requirements. The special design of the fluid path enables the CIP and SIP capability.
All of the housing parts on the BIOCOR Series pump contain no horizontal areas, a critical consideration for sterile applications. Available with a 1.4435/316L polished stainless-steel wetted path, BIOCOR Series pumps provide superior containment and utilize four ball-lifting magnets that can be attached to the pump housing from the outside at the location of the four ball valves (available for B20 and B32 models only). With the use of magnets, the ball valves can be lifted from their seats, allowing the pump to be drained entirely without needing to be disassembled or removed from the application.
Aseptic pumps of the BIOCOR Series are built in compliance with the corresponding hygienics standards (EHEDG, FDA, Class VI, etc.). The special design with the integrated cleaning-system enables clean-in-place (CIP) and SIP sanitize-in-place (SIP) capability. In addition, the pumps are conform to ATEX. For the EHEDG confirmation every BIOCOR pump is equipped with a diaphragm sensor (code D1).
Since 1984, Almatec® has been manufacturing a variety of specialty pumps for supplying and circulating chemicals in the semiconductor industry. With its straight-through flow pattern technology, the Almatec FUTUR Series Air-Operated Double-Diaphragm (AODD) Pump is ideally suited for the special requirements of these applications.
FUTUR Series pumps are self-priming and dry run capable, and feature a compact, simple design with few parts. FUTUR Series pumps have housing parts machined from solid blocks for long-life performance, and are cleaned, assembled and tested in a cleanroom line. For every pump size and material option, the appropriate pulsation damper is available.
The FUTUR is currently available in four materials:
Almatec® AHD and AHS Series Air-Operated Double-Diaphragm (AODD) Pumps have been specially designed to provide a safe operation in high-pressure applications up to 15 bar (218 psig). A typical application of these pumps is filter press feeding
AHD Series pumps utilize an internal pressure booster while featuring the well-known Almatec ring-tightening structure. The “D” in AHD stands for Duplex, which means the reinforcement of the drive pressure is more than 2:1 by the internal pressure boosting stage. The maximum drive pressure of 7 bar (100 psig) allows the AHD to build up discharge pressures up to 15 bar (218 psig). AHD Series pumps are available in three sizes (AHD 15, 25 and 40) with maximum capacities of 4, 10 and 20 m3 /h (17, 44 and 87 gpm).
The AHS Series pump, which does not include an internal pressure booster, features an extremely rugged housing making it suitable for higher discharge pressures. The “S” in AHS stands from Simplex, meaning the drive pressure is transferred to the medium in a ration of 1:1. This makes the AHS Series ideal for a wide variety of applications under heavy load conditions – from low discharge pressures to high-pressure applications up to 15 bar (218 psig). Due to the 1:1 ratio of the drive/discharge pressure, the corresponding air pressure has to be supplied from the compressor itself or an external pressure booster, also offered by Almatec. AHS pumps are available in two sizes (AHS 15 and 25).
Users who need a high discharge pressure of 15 bar (218 psig) – no matter whether it is with an AHD pump with internal pressure transmission or an AHS pump that achieves the discharge pressure by means of an external booster – can do so with peace of mind that the pump has been specially designed for such pressure ranges and does not have to be held together by external reinforcements.
Almatec® MM Series Air-Operated Double-Diaphragm (AODD) Pumps have been specifically designed to meet the strict standards, regulations and operational requirements that govern the food and beverage industry. MM Series pumps are ideal for these applications because they feature food-grade wetted materials and a construction that enables clean-in-place (CIP) and sanitize-in-place (SIP) capabilities.
The design of MM Series pumps also incorporates soft redirections without rotating parts and shaft seals in the product chamber, a critical consideration for hygienic operations. This design feature, when combined with the pump’s gentle displacement principle, results in a pump solution that is ideally suited for a wide variety of food and beverage applications. MM Series pumps are offered in three pump sizes with different hygienic manifold options.
Due to their design, pumps with oscillating action produce a pulsating flow. While the double-acting design of the Almatec® E-Series pump with a direct pneumatic drive already greatly reduces pulsation, a self-regulating pulsation damper must be installed on the delivery side of the pump in order to obtain a virtually uniform flow.
The dampers are self-regulating. Like in Almatec pumps, the diaphragm merely serves as a barrier between the product and the air chamber and is, therefore, always without pressure. If the pressure on the product side drops due to changes in the operating conditions, the pressure on the other side of the diaphragm will decline accordingly. As soon as the pressure on the product side rises, the pressure on the other side will increase as well. This automatic adjustment optimizes the diaphragm setting and ensures a consistently good damping effect.
Almatec® screw-on pulsation dampers represent the latest generation of active pulsation dampers and can be simply screwed onto the pump. Additional connecting elements are not required. Screw-on pulsation dampers are available for E-Series and FUTUR Series pumps.
The E-Series ET damper is also available in a flange version. Appropriate size pulsation dampers are available for every pump. The wetted material is PE or PTFE (both also conductive). Damper heads are made of polyamide or PE conductive. As with Almatec pumps, the recessed housing bolts are tightened against a ring. The exterior is completely free of metal.
The FUTUR Series damper model D is also available in a stainless-steel version for the FUTUR S Series pumps.
The AT Series inline pulsation damper will be used for CHEMICOR Series pumps and the P Series damper will be used for BIOCOR Series pumps. The wetted material of the housing is SS316 and the non-wetted damper head is made of PE conductive (ATEX).
Since its founding in 1984, Almatec Maschinenbau GmbH has concentrated on continuously defining the current state-of-the-art in pneumatic (air-operated) diaphragm pumps via extensive product enhancements and innovations.
Based on the extensive experience with the A-Series pumps, the E-Series plastic air-operated double diaphragm (AODD) pump was developed in 2009. The result and the name capture the spirit of Almatec's vision: E = economic, efficient, ecological.
