Designed for liquid and slurry transfer in chemical process applications

The Almatec E-Series represents the latest generation of plastic air-operated double diaphragm pumps made in solid design. Compared to the predecessor A-Series the following advantages are especially to mention:
-
further increased pump safety due to innovative ring-tightening structure
-
increased capacity
-
decreased air consumption
-
reduced noise level
-
optimized flow pattern
-
pulsation damper suitable for flange connection

As common, the housing parts are tightened to each other via housing bolts. However, instead of single bolts pressing punctually against the housing, all housing bolts are now tightened against a diaphragm-sized ring per side. This structure results in a more even spreading the housing bolt force and in an increased permissible bolt torque - in the end an increased pump safety which is assisted by further improvements of construction details.
The flow resistance is reduced via an optimised flow pattern to increase the efficiency factor of the pump. Compared to the A-Series, the same air flow achieves a higher fluid flow, respectively less air flow is required from the same fluid flow.
The pulsation damper can still be used an integrated model on top of the pump. However, an additional version with flange connection is available.
For the E-Series pumps are differnet materials available:
-
Housing: PE, PE conductive, PTFE, PTFE conductive
-
Diaphragms: EPDM, PTFE/EPDM, NBR
-
Ball valves: EPDM, PTFE, NBR, stainless steel
-
Cylinder valves: PTFE
E-Series pumps made of PE conductive and PTFE conductive meet the ATEX requirements of the directive 94/9/EG.
The seven pump sizes (the 3“ pump E80 is new) achieve the following max capacities:
-
0,9 m³/h, 15 l/min, 4 gpm (E08)
-
1,4 m³/h, 23 l/min, 6 gpm (E10)
-
3,4 m³/h, 55 l/min, 15 gpm (E15)
-
8 m³/h, 130 l/min, 35 gpm (E25)
-
20 m³/h, 330 l/min, 88 gpm (E40)
-
36 m³/h, 600 l/min, 160 gpm (E50)
-
48 m³/h, 800 l/min, 210 gpm (E80)

Particular attention has been paid to the form of the product chambers when designing the CHEMICOR metal air operated double diaphragm (AODD) pumps from Almatec. Result: soft contours, smooth flow channels and no dead spaces.
The three pump sizes in the CHEMICOR series permit a maximum delivery volume of 4.5 m³/h (AD 20), 9 m³/h (AD 32) and 24 m³/h (AD 50).
A variety of materials is available for the metal Almatec pumps:
-
Housing - stainless steel precision casting 1.4408, 1.4408 polished
-
Diaphragms - EPDM, PTFE/EPDM
-
Ball valves - EPDM, PTFE

Designed for sterile applications within the pharmaceutical, biotechnical and food industry

|
The ALMATEC BIOCOR air-operated double diaphragm pump series is especially designed for sterile applications within the pharmaceutical, biotechnical and food industry. The air-operated diaphragm pumps are EHEDG certificated as well as EC1935/2004 and ATEX conform. The special design with the integrated cleaning-system enables the CIP (clean in place) and SIP (sterilization in place) capability.
Always a demand for sterile applications: all housing parts of the BIOCOR pumps show no horizontal areas. Each pump comes with four ball lifting magnets, which can be attached to the pump housing from the outside at the location of the four ball valves. The ball valves are risen up magnetically out of their seats and the pump is drained entirely without having to be dismounted. There are no mechanical ball lifters with parts and seals in the wetted area (ball lifting magnets for B 20 and B 32 only).
The three pump sizes B 20, B 32 and B 40 achieve max. capacities of 3.5/7.5/17 m³/h (15.4/33/75 gpm) resp. a max. discharge pressure up to 7 bar (100 psig). The material for the wetted housing parts is electro polished SS 316 L (Basel Standard II, ferrit content < 1%) with a surface roughness of ≤ 0.4 μm. The center block is made of polyethylene conductive.
