3.3 System Design. 3.3.1 System Design and Installation. When incorporating any pump into a system it is considered good practice to minimize piping runs and the number of pipe fittings (tees, unions, bends etc.) and restrictions. Particular care should be taken in designing the suction line, which should be as short and straight as possible with a minimum of pipe fittings to minimize restricting product flow to the pump.
WARNING WARNING v) It is recommended that all piping and associated equipment from the tank to the discharge point is thoroughly cleaned before installation of the pump to avoid the possibility of debris entering the pump and causing damage. vi) Pressure gauges should be installed adjacent to the pump suction and discharge connections such that system pressures can be monitored.
(viii) When installing a pump complete with baseplate, motor and drive the following guidelines must be observed: a) The preferred drive arrangement for any rotary lobe pump is in-line direct coupled. If an alternative is required please contact Viking Pump or your Viking Pump distributor. b) Flexible couplings must always be incorporated and correctly aligned within the limits recommended by the coupling manufacturer.
- Ensure lubrication is provided for both pump and drive. Duralobe® pumps are shipped without oil and should be filled to the level of the oil sight glass which must be installed in the upper tapped hole in the side of the gearbox cover, refer to section 5.3 for pump oil capacities and grades. - If an external relief valve is incorporated in the system check that it is set correctly. For start up purposes it is considered good practice to set the relief valve lower than the system design pressure.
3.5 Shutdown Procedure. When shutting the pump down close both the suction and discharge valves and ensure that the necessary safety precautions are taken: 3.6 WARNING 3.7 - The prime mover power source has been isolated. - If installed, the pneumatically operated integral relief valve has been depressurized. - If Installed, flushed product seal auxiliary services have been isolated and depressurized. - Pump head and piping have been drained and purged. Routine Maintenance.

3.8 Integral Pressure Relief Valves see Figs 11, 12, 13 and 14. All models in the Duralobe® series can be supplied with integral pressure relief valves with both spring and air loaded versions available. The function of the valves can be further enhanced with the option of manual or airlift override offering particular benefits where CIP or SIP is employed.
WARNING WHEN THE VALVE OPENS, BECAUSE THE VOLUME OF FLUID CIRCULATING IS RELATIVELY SMALL, THE TEMPERATURE OF THE FLUID IN THE PUMP CHAMBER MAY RISE IF THE PUMP CONTINUES TO OPERATE FOR AN EXTENDED PERIOD. IN SEVERE CASES THIS MAY RESULT IN TEMPERATURES IN EXCESS OF THE PUMPS OPERATING LIMITS OR VAPORIZATION OF THE FLUID, BOTH OF WHICH SHOULD BE AVOIDED.
- The relief valve is now set. For Integral Relief Valve with Manual Lift - see Fig 12. - To operate the manual lift, turn the handwheel (111) clockwise which will lift the valve head (102/128). To resume normal operation turn the handwheel (111) counter-clockwise. For Integral Relief Valve with Air Lift - see Fig 13. To actuate the air lift connect an air supply not exceeding 105 psi for S1, S2, S3 and 150 psi for S4 to the cylinder (123) which will lift the valve head (112).
Danger Under no circumstances should any attempt be made to dismantle a pressure relief valve which has not had the spring pressure relieved, is still connected to a pressurised air supply, or is mounted on a pump that is operating. Serious personal injury or pump damage may occur. Fig 11 Spring Loaded Integral Pressure Relief Valve S1, S2, S3 Typical.
