Page 3: Introduction
In the second figure, liquid is drawn in by the left-hand diaphragm and displaced by the right-hand diaphragm. The appropriate use of an Almatec air-operated double diaphragm pump of the AHS series refers to the liquid (or sludge) transport taking into account the operation parameter mentioned in this manual and in compliance of the given terms for commissioning, operation, assembly, disassembly and maintenance. -

Page 8: Connecting The Air Supply
When installing the pump into boards or cabinets, it has to be ensured that cold air does not get caught behind the muffler. ALMATEC heavy duty pumps do not require any lubrication. It has to be secured, that no oil can enter the pump. -
Page 9: Start-Up And Operation Of The Pump
Moreover the feeding of filter presses is a possible application field. The ideal combinative effect of ALMATEC AHS pumps and filter presses is illustrated very well by the automatic adaptation to pressure and flow rate. When beginning to fill the empty press, the low discharge pressure results in a high flow velocity for fast filling. - Page 10 • Especially when deliver critical liquids, wear parts, like diaphragms, should be replaced within a preventive maintenance. • The use of non-original ALMATEC spare parts and structural changes lead to the lapse of the warranty immediately. When operating such a pump, damages of properties and/or persons cannot be excluded.

(if compatible with rinsing agent) to facilitate the separation after a certain waiting period. The general design of the ALMATEC AHS pumps is simple. Every pump comes along with a mounting tool for the air-valve system [25]. Take out the muffler [23] installed onto the center block [18] before dismantling the pump to protect it against damages during the disassembly. -

10.2. Diaphragm monitoring (optional equipment code D) Although ALMATEC diaphragms with integrated metal core are designed for an optimum service life, the diaphragm remains a wear part. If it breaks, liquid can leak into the center housing and possibly emerge through the muffler. This can be prevented simply and effectively with the ALMATEC diaphragm monitoring. -
