ALMATEC F-Series F 10 / F 20 Operating and Installation Instructions ought to be studied before installing the pump Original Instruction Introduction ALMATEC air-operated diaphragm pumps are constructed according to the state of the art and they are reliable. Imminent danger by operating error or misuse can lead to damages of properties and/or persons. The pumps are to be applied for the intended use and in a safety-related proper condition only. Each person working on the ALMATEC air-operated diaphragm pumps concerning installation, start-up, handling or maintenance has to read this manual completely and in an attentive way and has to follow all mentioned procedures and safety notes. General description of the machine, appropriate use and residual dangers The ALMATEC F-Series pumps are oscillating positive displacement pumps and are based on the functional principle of double diaphragm pumps. The design includes two separated liquid chambers as well as an integrated pulsation damper. The basic configuration consists of two external pump housings with a center housing between them. Each of the side housings contains a product chamber which is sealed against the center housing by a diaphragm. The two diaphragms are interconnected by a piston rod. Directed by an air control system, the diaphragms are alternately loaded with compressed air so that they move back and forth. So the liquid is displaced or drawn in. In addition a pulsation damper smooths the liquid flow in the left product chamber. The appropriate use of an Almatec air-operated diaphragm pump refers to the liquid 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. Even if all necessary safety measures described in this manual have been met, a residual danger exists by leakages or mechanical damages. At sealing areas or connections liquid can be released uncontrollably then. Storage In general the ALMATEC pump is delivered operational and packaged. If the unit is not installed right away, proper storage conditions are important for a trouble free operation later. The pump has to be protected from wetness, coldness, dirtying, UV-radiation and mechanical influences. The following storage conditions are recommended: - Steady ventilated, dust and vibration free storage room - Ambient temperature between 15°C and 25°C with a relative humidity below 65% - Prevention of direct thermal influences (sun, heating) 1

Code system The ALMATEC Maschinenbau GmbH is certified as a modern, quality-orientated enterprise according to DIN EN ISO 9001:2008 and 14001:2005. Before release for dispatch, any pump has to undergo an extended final control. As a general rule in the countries of the EU only such machines are allowed to take into operation, which are determined to meet the regulations of the EU machinery directive, the harmonized standards, European standards and the respective national standards. Hence the operator has to verify whether the ALMATEC pump manufactured and delivered properly according to...

Installation and Start-up The correct installation procedure is based on the „Dimensions and connection plan ALMATEC F 10 and F 20“ on page 7. ALMATEC pumps of the F-Series are pneumatic diaphragm pumps with integrated pulsation damper and two separated product chambers. air supply suction delivery chamber discharge extractor resp. circulation chamber discharge extractor resp. circulation chamber alternative suction extractor resp. circulation chamber discharge delivery chamber The actual transport of the liquid is realized by the delivery chamber. To smoothen the flow, the fluid passes an...

The operator is responsible for an adequately stability and an appropriate fixation of the piping according to the state of the art. To facilitate the installation and maintenance shut off valves should be installed right before and after the pump. The nominal width of the connection pipes has to be chosen in accordance to the connections of the pump. A smaller piping can cause cavitations (suction line) as well as a loss of performance (suction and discharge line). In case the pipe is too big, the dry suction capacity of the pump can decrease. Seal the suction line diligently; hosepipes...

„h Pressure tests of the plant a pump is included in may only be d isconnected from the pressure on both ports or by using the pressure the pump develops while operating. The load of a pressure in the plant may damage the pump. „h Pump must not be operated with a positive suction pressure. „h Depending on the conditions of opera t hrough the muffler in case of a diaphragm rupture (in this case muffler has to be replaced). For further safety requirements the optional equipment diaphragm monitoring and barrier chamber system are recommended. „h In case of a diaphragm rupture, it might be...

Additional temperature hints The temperature and pressure limitations listed on page 2 are solely based on mechanical temperature limits of the housing material used. Depending on the fluid pumped, the maximum safe operating temperature of the housing material can be reduced significantly. A general aspect of lower temperatures is, that below 0°C cold-brittling of the elastomers used within the pumps can results in accelerated wear. Regarding the housing materials, please note that PE - other than PP - keeps its mechanical strengths at low temperatures and PTFE keeps mechanically stable as...
