Page 10: Assembly And Function
This pump type represents this product in its simplest form and transfers media at the fixed flow rate. NF 100.27 version (fixed flow rate with overpressure limiting) If the diaphragm liquid pump is operating against a closed system, the delivery pressure quickly exceeds the maximum permissible value. - Page 11 Diaphragm liquid pump NF 100 Assembly and function NFB 100 version (double-headed pump with fixed flow rate) This pump type has two NF100 pump heads that can be operated individually or together (see Chapter 6.3.2).

- Page 15 Diaphragm liquid pump NF 100 Installation and connection KNF recommends mechanically decoupling the pump from the Decoupling piping system. This can be achieved with flexible hoses or pipes, for example. This prevents any oscillations of the pump being transferred to the system.
- Page 16 Diaphragm liquid pump NF 100 Installation and connection 6.2. Electrical connection For pumps with alternating current motors: Risk of electric shock, danger of death Only have the pump connected by an authorized specialist. Only have the pump connected when the power DANGER supply is disconnected.
- Page 17 Diaphragm liquid pump NF 100 Installation and connection Supplemental circuit In order to ensure that emissions comply with the EN 55011 or EN for brushless DCB motors 55022 emission standards, this pump type with a brushless DC motor DCB must be fitted with a supplemental circuit. The supple- mental circuit must be installed as close as possible to the motor.

Page 25: Servicing
Flush the pump with a neutral liquid and pump empty. 8.2.1. Flushing the pump When transferring aggressive media, KNF recommends flush- ing the pump with air (or an inert gas if necessary for safety reasons) under atmospheric conditions for a few minutes be- fore switching off in order to extend the service life of the dia- phragm. - Page 26 The method of assembly which follows will differ according to the pump type used. For this reason, please proceed with the section (NF 100 and NFB 100 versions or NF 100.27 ver- sion) that corresponds to the pump type you are using.
- Page 27 Diaphragm liquid pump NF 100 Servicing NF 100.27 version Insert resonating diaphragm.27 (15) in the connecting plate (5). Place the diaphragm.27 (14) centrally on the resonating dia- phragm.27 (15). Place the compression spring.27 (13) over the thread of the diaphragm.27 (14).
