Page 6: General
This instruction manual will familiarise operators with detailed information about installing, operating and maintaining of the pump. The Tapflo pump for filter press feeding is a very compact unit that can be mounted directly to the filter press. The design and function allows the user a straightforward pressing of slurries. -
Page 7: Installation
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 8: Lifting And Transportation
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. IOM manual Tapflo TF series... -

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. IOM manual Tapflo TF series... -

Air pressure The maximum air feed pressure for Tapflo TF pumps is 8 bar for sizes TF50, TF70, TF100 and TF120, 7 bar for TF220 and 6 bar for sizes TF200, TF420 and TF400. This is the air pressure that is supplied to the pressure booster. -
Page 11: Noise Level
1.7.4. Noise level At tests, the noise level from a Tapflo pump has not exceeded 85 dB(A). Under some circumstances, for example if the pump is operating under high air pressure at low discharge head, the noise can be inconvenient or hazardous for personnel staying for long periods in the vicinity of the pump. -
Page 12: Air Connection
3) Needle valve to adjust the air flow (especially when operating the pump in the lower range of performance); It is recommended to install the needle valve between the booster and pump 4) Filter. These components are included in Tapflo’s Air treatment system which can be ordered from 1.8.2. Pressure ratio 2:1 The pressure booster has the function to transmit the primary pressure (from air supply) to an output pressure of up to twice as much. -
Page 13: Scope Of Supply
Even if all above safety instructions are met and complied with, there still exists a minor danger in the event of a leakage or mechanical damage of the pump. In such case the pumped product can emerge on sealing areas and connections. IOM manual Tapflo TF series... -
Page 14: Operation
For instance, a TF100 pump should run continuously at maximum 50 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 15: Booster Operation Conditions
This is essential to keep the diaphragms in balance what protects them from premature failure. 2) By cutting off the air supply. NOTE! When using this method make sure that the discharge valve is opened to relief the pumps pressure. IOM manual Tapflo TF series... -

Page 28: Test Run
We recommend you to conduct a test run of the pump before installing it in the system, so no liquid gets wasted if the pump leaks or perhaps does not start accordingly to wrong assembly of the pump. After a few weeks of operation retighten the screws with appropriate torque. IOM manual Tapflo TF series... -
Page 29: Standard And Options
4.1. Standard As a standard Tapflo TF pump is equipped with a Festo pressure booster equipped in two manometers and a pressure regulator. By using the knob we can regulate the output pressure. Maximum pressure increase is 2:1. Differential pressure must be at least 2 bar. -
Page 30: Air Treatment System
+ mounting bracket 4.5. Pump prepared for booster assembly Tapflo pumps can be fitted only with reinforcement plates prepared for booster assembly but without the booster itself. The pump will also have assembled the hybrid air valve with PET piston. This way the pump is prepared for high pressure applications and the end user can install the booster on the pump by himself. -
Page 31: Pump With Aluminium Centre Body
To increase pump lifetime for high applications we recommend to use pumps with aluminium centre body. This material is more resistant to high pressure than our standard PP. For this option, please use “6A” in pump code, e.g. T100 PTT-6A. IOM manual Tapflo TF series... -
