- Page 9 1.1. Operation principle The Tapflo diaphragm pump is driven by compressed air. The two diaphragms are connected by a diaphragm shaft and pushed back and forth by alternately pressurising the air chambers behind the diaphragms using an automatically cycling air valve system.
- Page 10 INSTALLATION 1.3. Lifting and transportation Before handling the pump check the weight of the pump (see 6.4. ”Technical data”). Refer to Your local standards on how to handle the pump. If the weight is excessive to transport by hand it must be lifted using slings and a suitable lifting device e.g. a crane or forklift.
- Page 11 INSTALLATION 1.6. Suction and discharge piping Suction and discharge piping should be fully supported and anchored near to but independent of the pump. The piping to the pump should be a hose, to prevent undue stress and strain on the pump connections and the piping. 1.6.1.
- Page 12 1.7.1. Protection In the interest of health and safety it is essential to wear protective clothing and safety goggles when operating, and/or working in the vicinity of Tapflo pumps. 1.7.2. Explosion hazardous environments – ATEX The “TX” Aseptic EHEDG series pumps are designed to operate in environments where there is danger of explosion.
- Page 13 1.7.3. Air pressure The maximum air pressure for Tapflo pumps is 8 bar. Higher air pressure than 8 bar can damage the pump and may cause injury to personnel in vicinity of the pump. If you intend to apply a higher air pressure than 8 bar, please consult us.

- Page 16 1.10.2. Self-priming The Tapflo pump is designed to pull a high vacuum. It is able to evacuate an empty suction pipe without any damage to the pump. The suction lift is up to 5 meters (16.4 ft.) from an empty suction pipe and up to 8 meters (26.2 ft.) from a wetted pipe. The suction capability depends on the pump size (see chapter 6.
- Page 17 For instance, a TX94 pump should run continuous at maximum 40 l/min. ➢ As stated in chapter 1.8.1. Tapflo recommends to use an appropriate air treatment system in order to extend the pump’s lifetime.
- Page 18 OPERATION particulate matter contained in the liquid will be deposited and get stuck inside the pump chamber. Therefore after finishing work the pump must be emptied of the remaining fluid. Otherwise, when starting the pump again, the diaphragm may get damaged and the shaft may bend leading to grub screw fracture.
- Page 19 2.7.1. CIP and SIP The importance of easy cleaning is essential in hygienic applications. Tapflo aseptic pumps are designed for CIP (Cleaning In Place) and SIP (Sterilization In Place). This allows the pump to be internally cleaned without disassembly. The pump can be cleaned by flushing through with a CIP fluid (usually a mild solution of sodium hydroxide and a sanitizing additive) or by injection of hot steam (SIP).
- Page 20 The characteristics of the liquid, temperature, materials used in the pump and running time decide how often a complete inspection is necessary. Nevertheless, Tapflo recommends to inspect the pump at least once a year. Parts from KIT AIR and KIT LIQ should be changed during inspection. See paragraph 5.7. „Stocking recommendations”...

- Page 28 OPTIONS 4.1. Magnetic ball lifters New magnetic ball lifters have been implemented in pump sizes TX94 – TX244. They are implemented to enable pump emptying when no other draining option is available. Rotating the pump is no longer needed. The balls are lifted by simply attaching the magnets to the pumps manifold.
