AODD Pumps More Power for Filter Presses
Almatec's portfolio of sanitary AODD pumps has a newcomer: The high-pressure pump series AHD/AHS are well suited for filter presses with an internal pressure booster and a proven ring-tightening.
The “D” in AHD stands for Duplex, meaning the reinforcement of the drive pressure is more than 2:1 by the internal pressure boosting stage. A maximum drive pressure of 7 bar (100 psig) allows 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 new AHS Series, 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).
