Improvements in the Almatec Diaphragm Pump Range
While the basic principles of air driven double diaphragm pumps has not changed for decades, Almatec have been at the forefront of development and innovation which have led to these pumps been accepted in many industries.
Developing from the successful Almatec AD Series this A-Series pump range offers a large number of new advantages including increased performance and reduced running costs in terms of lower maintenance and a 40% reduction in air consumption.
The A Series is designed with a number of revolutionary features. Constructed with only three solid housing parts in either PTFE offering almost universal chemical resistance or UHDPE which in addition to its excellent general chemical resistance is also suitable for use with highly abrasive products the pump can be quickly disassembled for ease of maintenance. Further, the central housing part can be rotated allowing for three alternative port configurations
Bi-directional Diaphragm Clamping
The already unique, totally sealed, Almatec’s one piece diaphragms which are manufactured in their priming position to optimise efficiency and reduce air consumption have been improved still further by the introduction of the bi-directional damping system. The new labyrinth-like system not only squeezes the diaphragm between the pump housings but also seals in the axial and radial planes.
This maintains the clamping force even when large tolerances occur in the pump housing, for example due to loose housing bolts. This reduces maintenance time and increases safety.
Air Distribution System – Improved Efficiency & Reduced Noise Emissions
One major problem with all air driven double diaphragm pumps is their sound emission. While much of this noise is unavoidable being caused by the expansion of air, the Almatec A Series contains a number of built in features designed to reduce the level of disturbance to a minimum.
A further feature is the Perswing P® air control system. This is a metal-free, pneumatically pilot-operated control system which, with only two moving parts ensures that there is absolutely no dead centre, excluding the risk of pump stalling. This also results in a 40% reduction in air consumption and a drastic reduction in noise emissions.
