Benefits of Using Original Almatec Parts

Barrier Chamber System (Code BS)

The Almatec barrier chamber system meets high-safety requirements. The individual diaphragm is replaced by two diaphragms arranged in tandem with a barrier chamber of conductive PE between them and filled with non-conductive liquid. A change in conductivity of the barrier liquid is detected by sensors and signaled to a controller, which triggers an alarm or disconnects the pump.

Stroke Counting (Code C)

Almatec air-operated diaphragm pumps can be used continuously (24-hour operation) or intermittently for hours, for minutes or for an exact defined number of strokes. To accurately count the strokes, a sensor can be installed in the pump's center housing (also available as pneumatic version).

Diaphragm Monitoring (Code D)

A capacitive sensor installed in the pump muffler detects all liquids and in case of a diaphragm rupture it outputs a corresponding signal to a controller which then triggers an alarm or disconnects the pump via a connected solenoid valve.

Flange Connection (Code F)

Almatec E-Series flange connections

According to recognized industry safety standards, all E-Series pump sizes from E 15 to E 50 can be equipped with thread bushings and flange O-rings for flange connections DIN or ANSI / PN 10. For the AH Series pumps, the flange connection DIN or ANSI / PN 16 is standard.

Draining System (Code R)

E-Series pump sizes E 15 to E 50 are available with a special Almatec draining system consisting of a bypass system in the side housings that can be activated easily either via hand-operated valves or pneumatically. In this way, the pump and piping can be drained without having to be dismounted. The amount of cleaning agent and solvent required when changing products is considerably reduced, and this greatly reduces environmental pollution. For metal CHEMICOR pumps, another constructive solution is available. Ball lifters – which are turnable by hand – are fitted to the four ball valves. By turning the handles, the ball valves are lifted out of their seats.

Pneumatic Expansion Compensation (Code EC)

Temperature changes can cause thermal expansion to occur in air-operated double-diaphragm (AODD) pump units engineered with plastic housings and metallic connecting elements. Operating in wide temperature ranges – including many PTFE pump standard applications – can lower the tension of the connecting elements. Therefore, Almatec has introduced an “Expansion Compensation” option for its line of E-Series AODD pumps (code EC for E-Series pump sizes 15/25/40/50).

Special Diaphragms (Code L and P)

For the use of the pumps in the device group IIC (European ATEX regulation) without flanking measures diaphragms made of conductive PTFE/ EPDM compound are available (code L). For liquids with increased diffusion tendency (e.g. benzene, solvents) PTFE/EPDM compound diaphragms made of modified PTFE are obtainable (code P).

EC1935/2004 Certification (Code H)

Since certifications are an important aspect in the hygienic market, an EC1935/2004 conformity declaration can be issued for Almatec pumps with PTFE internals for the applicability of the pump material for food contact.

USP Class VI Certification (Code USP)

After receiving an increasing number of requests to state “USP Class VI” conformity for the wetted pump materials, Almatec has introduced the “Option Code USP” for defined material types. Whenever ordering such a pump, the customer can be sure to receive a clearly marked pump together with an according certificate. Please contact us for more information about the concerned pump material codes.

Transport Carts

Many industrial applications need not only stationary air-operated diaphragm pumps but also mobile pumping units (e.g. for use as an emergency pump, as a short-dated replacement for a pump to be repaired or for decanting between two containers). For these purposes, a transport cart is available.
