Page 9: Introduction
INTRODUCTION The MP48-R diaphragm pump is suitable for 100% oil-free delivery of corrosive gases. Its perfor- mance and design are specially adapted to the requirements of the analysis technology. The pump is gas-tight and operates maintenance-free. PROPER USE The MP48-R is exclusively intended for transferring gases and vapors. Install and operate the pumps only under the operating parameters and conditions described in chapter The pumps may only be operated when fully assembled. -
Page 10: Area Of Application
AREA OF APPLICATION All parts of the MP48-R diaphragm pump that come into contact with the medium are made of PTFE or FFPM. The pumped gas remains analytically pure due to the absolutely lubricant-free operation of the pump. A special diaphragm and valve system ensures freedom from maintenance and a long service life. -
Page 11: Ambient Conditions
AMBIENT CONDITIONS The following ambient conditions must be complied with during operation: Ambient temperature range during operation: +5 to +60 °C [41 to 140 °F], 0 °C [32 °F] if not condensing (frost-free). The pumps must be protected from the effects of water and dust. ... -

Page 14: Design And Function
DESIGN AND FUNCTION To adjust the flow rate, a throttle valve (Figure 3/7) is installed in the pump head as an internal pump by-pass. All wetted parts are made of modified PTFE, PTFE and FFPM. 1 Pneumatic pump outlet 2 Pneumatic pump inlet 3 Pump head 4 Motor 5 Capacitor... -

The elastic diaphragm (Figure 4/4) is moved up and down by the eccentric (Figure 4/5) and the connec- tion rod (Figure 4/6). In the downward stroke it aspirates the gas to be transferred via the inlet valve (Figure 4/2). In the upward stroke, the diaphragm presses the medium out of the pump head via the outlet valve (Figure 4/1). -
Page 16: Installation Instructions
INSTALLATION INSTRUCTIONS When installing the pump make certain that accident prevention regulations and safety instructions in- cluding those for subsequent operation are observed. The safety instructions in chapter 3 must be ob- served. Observe the relevant safety regulations for the pumped media. To avoid disturbing heat accumulation, the pump should be installed away from heat sources and freely ventilated. - Page 17 Make sure, that the installation location is accessible for maintenance and service. The IP protection class of the pump motor is indicated on the type plate. Condensate accumulated inside the pump head destroys the pump. Condensate can form, for example, if the pressure dew point is ex- ceeded or if there is a malfunction in the sampling process.

Among other things, this reduces the pump capacity. MP48-R | 1.00.00 www.mc-techgroup.com... -
Page 19: Figure 6 Compressor Housing
To ensure optimum suction performance, it is advisable to align the pump head downwards so that the condensation can simply run out of the pump head. To do this, the compressor housing and pump head (depending on the installation situation) can be rotated and assembled in 90° increments. 1 Housing cover 2 Allen screw 3 Eccentric... -

Page 21: Attaching Connection Cables
Incorrect mains voltage can destroy the device. When connecting, ensure that the mains voltage is correct according to the information on the type plate! The supply voltage may deviate by Note max. +6 % or -10 % from the specifications on the type plate. When installing power installations with nominal voltages up to 1000 V, the requirements of VDE 0100 and its relevant standards and regula- tions must be observed! -

Permitted deviation of the supply voltage see chapter 9 Technical data. Note 2. Open terminal box cover. 3. Connect the earth (ground) wire to the motor. 4. Connect the mains cables to the connections L1 and N of the pump motor. Figure 8 Electrical connection of the pump 5. -
Page 23: Connecting The Pump
M&C recommends to mechanically decouple the pump from the piping system, e.g., by using flexible tubes or hoses. In this way, possible vibrations and noise from the pump can be avoided being transmitted to the system. 12.4.1 CONNECTING THE PUMP The pneumatic connection to the diaphragm pump is located on the top of the pump head. - Page 24 Connect the optionally available tube fittings as follows: 1. Loosen the union nut of the compression fitting by turning it counterclockwise, carefully remove the nut from the fitting body. Be careful not to lose the compression ring that is loose in the nut. 2.

The diaphragm pump is designed so that the flow rate can be adjusted to suit the analysis system it is supplying. If it is necessary to adjust the flow, proceed as follows (see Figure 10): Figure 10 Self-locking adjusting screw X for setting the flow rate To reduce the flow Turn the adjusting screw X anti-clockwise. -
Page 28: Maintenance
Aggressive media Aggressive media lead to burns during decommissioning. Warning Flush the pump under atmospheric pressure conditions with inert gas. If there is no danger of explosion, flushing can also be carried out with air. Aggressive media residues possible. ... -
Page 29: Cleaning The Pump
CLEANING THE PUMP When cleaning, make sure that no liquids enter the inside of the housing. Note Flushing the pump When transferring aggressive media, flush the pump under atmospheric conditions some minutes with air (or, if necessary, for safety reasons, with an inert gas) prior to switch-off to increase the service life of the diaphragm. -
