Page 4: Danger Of Pump Damage
If the pump has pumped hazardous gases it will be absolutely necessary to determine the nature of the hazard involved and take the appropriate safety precautions. Take adequate safety precautions prior to opening the intake or exhaust port. Respect the instruction concerning environment protection when discarding used oil or exhaust filters. -
Page 5: Description
The anti-suckback valve, gas ballast valve, exhaust filters, oil feedback circuit, oil cooler and thermal switch are integrated functional elements of the SRV630. The rotor mounted eccentrically in the pump cylinder has three vanes which divide the pump chamber into several compartments. The volume of each change periodically with the rotation of the rotor. - Page 6 The oil cycle of the pump is maintained by the pressure difference existing between the oil casing (pressure above atmospheric pressure) and the intake port (pressure below atmospheric pressure). Unintentional venting of the vacuum chamber as well as oil suck back when switching off the pump is prevented by the built-in anti-suck back valve.

Page 10: Mounting Orientation
The pump oil is wrapped in plastic film with 5 desiccant bags inside. The connection ports are blanked off by plastic protective caps or self-adhesives. Take these caps or self-adhesives away before turning on the pump. The pump is filled with oil. 3.2 Mounting orientation Pumps which have been filled with oil must only be moved in the upright position (horizontally). -
Page 11: Operation
If the pump has been shelved for over one year, standard maintenance must be done and the oil must be exchanged too before the pump is put in to service once more. Operation It is essential to observe the following instructions step by step to ensure safe start-up. - Page 12 ★ The maximum pressure at the inlet may not exceed atmospheric pressure (about 1013 mbar). Never operate the pump in the presence of over pressures at its intake. ★ The cross-section of the intake line should be at least the same as the one for the intake port.
- Page 13 ★ Never operate the pump with a blocked or restricted exhaust line. ★ The SRV630 does not have an exhaust flange. For the connection method of the exhaust pipe, refer to the SRV630 installation dimension drawing. The cross-section of the exhaust line should be at least 100mm. If the exhaust line is too narrow, overpressure or overheating may occur in the pump.
- Page 14 ★ For the check, switch on the motor briefly. If it starts up with the wrong direction of rotation, switch it off immediately and interchange two phases of the connection. It is recommendable to check the direction of rotation with a phase sequence indicator.（The motor steering can be determined by the fan steering at the motor shaft end.

Page 15: Start-Up
The normal oil level is between the middle and the top of the oil window. ★ The SRV630 pump is not designed for starting under 12 ° C. ★ Before the pump starts, ensure that the connected accessories meet your application requirements and ensure safe and reliable operation. - Page 16 The gas ballast valve is opened by a screwdriver. The running noise of the pump is slightly louder if the gas ballast valve is open. Before pumping vapors ensure that the SRV630 has warmed up for approx. 30 min. with closed intake line and with open gas ballast valve.
- Page 17 ★ One sign of condensation of vapors in the pump is a rise of the oil level during operation of the pump. ★ When vapors are pumped, the pump must not be switched off immediately after completion of the process because the condensate dissolved in the pump oil may cause changes or corrosion.

allow the pump to continue to run.（see chapter 4.4） 。 ★ When the pump has been switched off due to overheating, initiated by the motor or its temperature detector, the pump must be cooled down to the ambient temperature, and must only be switched on again manually after having eliminated the cause. -
Page 19: Maintenance Intervals
★ Depending on the process involved, dangerous substances and oil may escape from the pump. Take the necessary safety precautions. ★ Respect the instruction concerning environment protection when discarding used oil or exhaust filters. ★ Observe the safety regulation. ★ Do not use deformed or damaged seals. Use new seals. ★... -

Replacing the pump module Disassembling and reassembling the pump module Control belts 6 months Lubrication bearing Cleaning the radiator fan To simplify the maintenance work we recommend combining several jobs. 5.3 Maintenance work A Oil level The pump’s oil level during operation must always be between the middle and top edge of the oil-level glass When necessary, switch off the pump and add the correct quantity of BSO-100 oil. - Page 21 temperature. If there is a risk of the oil being polymerized by the connected process, change the oil immediately after operation of the pump. Pump when operating is hot and some surfaces could reach a temperature higher than 80° C (176 °F). There is a risk of burn by touching. Take note of the warning labels on the pump.
