In addition to standard plastic and metal air-operated double-diaphragm (AODD) pumps, Almatec® also offers AODD pumps specifically designed to meet the requirements of special applications, including biopharma (BIOCOR Series), semiconductor (FUTUR Series), high-pressure (filter press feeding, AHD Series), as well as food and beverage (MM Series).

BIOCOR Series

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. 

Features and Benefits

• Engineered in accordance to the essential specifications (EHEDG, FDA, CLASS VI, etc.)
• Sistem pembersihan terintegrasi yang unik
• Kemampuan Clean-in-place (CIP) dan sanitize-in-place (SIP)
• Disesuaikan dengan ATEX

FUTUR Series

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:

·        Four sizes made of PTFE/PE for acids and caustics up to 130°C (266°F) (FUTUR T model)

·         Two sizes made of PTFE for hot applications with acids and caustics up to 200°C (392°F) (FUTUR H model)

·         Two sizes made of PE for slurries (FUTUR E models)

·         Two sizes made of SS316L for solvents (FUTUR S and SH models)

Features and Benefits

• All plastic models contain no metal
• Temperature range up to 200ºC (392ºF)
• Patented, contactless cascade sealing between the product chambers
• No O-ring sealing in wetted areas

AHD/AHS Series

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.
