Page 3 Correct use of ALMATEC E series pumps: They shall operate within the operating parameters specified in this manual, and follow the instructions for commissioning, operation, assembly, disassembly and maintenance.
Page 4 Before delivery, each pump has undergone strict quality control with all manufacturing and inspection records properly maintained for traceability. Operators will verify whether ALMATEC pumps are produced according to the customer orders and meet relevant requirements during production. Therefore, before using the pump, ensure that the pump and its materials are suitable for the intended application and installation environment.
Page 5 ALMATEC air-operated diaphragm pumps made of conductive PE or PTFE are suitable for use in potentially explosive atmospheres of G (gas) or D (dust) in categories 2 and 3 (Zone 1 and Zone 2 respectively) as regulated by EU Directive 2014/34/EU.
Page 6 Installation location: Category D Inside the pump: Category G Conductive ALMATEC air-operated diaphragm pump can usually be used in the dust environment of class IIIC at the installation location (potential explosion area outside the pump, equipment category: D) Note! Inside the pump (equipment category G), the approved explosive dust class depends on the selected...

Page 10 The pump nozzle is located on the intermediate housing [4]. Configurations with different nozzle directions are available (only for models without threaded pulsation damper). When E series pumps are delivered, the standard configuration of the nozzle features a horizontal suction port at the bottom and a horizontal discharge port at the top (as shown in Figure 8.1).
Page 11 For low performance, it is recommended to use a needle valve for fine adjustment. For unloaded pump, it is recommended to start slowly (for example, using a needle valve). The E series pumps are self- priming during dry running, so there is no need to prime the suction port.
Page 12 Torque values Before starting the pump and after several hours of operation, it is suggested to tighten the housing bolt [19], the discharge valve plug [9] and the plug seat [11/13] according to the torque data in the table below. This is because the pump parts may creep under alternating stress. These parts shall also be checked and retightened after shutdown, temperature changes, transport, or after disassembling the pump.

Page 14 Notes on submerged installation If the E series pump is used as a submersible pump, please pay attention to the following suggestions: When the air-operated diaphragm pump is immersed in water, the exhaust port must be led out of the liquid surface with a pipe to ensure smooth exhaust of the pump.
Page 15 PE (not PP) retains its mechanical properties at low temperature, while PTFE can still maintain its mechanical stability over a wider temperature range. Therefore, ALMATEC E series pumps can operate safely at low temperatures. However, when conveying medium below 0℃ (32℉), the wear on internal parts will increase.
Page 16 Maintenance Only the original spare parts of ALMATEC shall be used for repair and/or preventive maintenance. Failing to do so will invalidate the CE and ATEX markings, the declaration of conformity, and the pump's warranty claims. All repairs to the pump must be carried out by trained professionals using appropriate tools.
Page 17 When disassembling the pump, be sure to follow the work flow and safety precautions described on pages 10-13. The only difference between the different sizes of the E series (E15 to E50) is the number of housing studs [19]. Additionally, for the E08 and E10 sizes, the drive shaft [20] also serves as the pilot piston for the air valve. In both E08 and E10 pumps, there are no drive shaft piston rings [22], set screws [21], or air filters [24].
Page 18 Figure 14.6 Figure 14.7 Figure 14.8 You can refer to the E series pump disassembly video on our website as follows: https://www.psgdover.com/de/almatec/download-library/videos Assembly The reassembly process of parts is basically the opposite of the disassembly process. Here are some additional reference information.
Page 19 Before putting the pump back into operation, be sure to check the tightness of the pump and the torque value of the bolt. There is a video about the assembly of E series pump on our website. https://www.psgdover.com/de/almatec/download-library/videos...

Page 30 Optional Configuration For special requirements, the ALMATEC E-Series air-operated double diaphragm pumps are available with various optional features. The pump code shows which optional features are available. The code is on the pump nameplate. Isolation chamber system (code: BS), with a separate operating manual. In the list of spare parts, all non-product contact parts are in italics.
Page 31 For optimal system performance, its air supply pressure shall not be less than 1.5 bar! Note that the air inlet for the stroke counter system is distinct from the air inlet for the pump. The positions of these two connections are listed below according to different types and specifications of pumps.
Page 32 However, it shall also be considered that the diaphragm monitoring system can not prevent the liquid from leaking out of the pump from the muffler. For higher safety requirements, it is recommended to select ALMATEC isolation chamber system (equipment code: BS). However, it shall be noted that high humidity in the surrounding air may cause false alarms, even if the pump air supply is dried.

Page 34 Food pumps (EC 1935/2004) (option code H) ALMATEC E series pumps are not designed for effective cleaning, but they are still widely used in the food industry. Pumps with option code H feature wetted parts compliant with EC 1935/2004 for food contact. These pumps are shipped with a special label and a declaration of conformity.
Page 35 Draining system (option codes R1, R2, R3, R4, R5, R6) Pumps equipped with a unique ALMATEC draining system can be drained via an inclined discharge pipe installed at the factory. This system is not suitable for flushing the pump with other liquids, nor for flushing through the suction port or discharge ports.

Page 37 Pumps with PTFE diaphragm and FKM housing gasket (option code V) FKM gasket features chemical resistance for most applications that require PTFE diaphragm (please check compatibility). These gaskets are highly elastic, provide excellent sealing properties, and are cost-effective.

Page 39 ALMATEC ET and ET-F series pulsation dampers represent the latest generation of active pulsation dampers, designed specially for conversion to ALMATEC E series air-operated double diaphragm pumps. It should be noted that the pulsation damper will reduce the actual flow rate of the pump depending on different working points.
Page 40 As long as the inlet and outlet of ALMATEC pump are horizontally aligned, the ET- damper can be easily installed on the E series pump without altering the pipeline. Make sure that the screw plug (part 13 in the pump exploded view) on the intermediate housing is in the correct position.
