Note : The first digit in the code No. indicates No. of pumping elements in the pump. The second letter indicates flow and pressure rating of the pumping elements.

Code No. 7C for example, indicates a pump with 7 pumping elements having rated flow of 24.5 l / min and operating pressure upto 250 bar.

Note : Torque limitation - The sum of torque used for the piston pump and torque used at extended shaft end should not exceed 148 Nm ( 22.2 kw @ 1450 rpm )

PRIMING PROCEDURE FOR CLOSED EXECUTION PUMP
A] When the Casing Pump is mounted Horizontally.

Case I : When the pump suction port height exceeds 300 mm above oil level. During assembly / installation provide a check valve with almost nil cracking pressure on the suction pipe. (Refer check valve model codes given below). Fill up the casing with oil (Use Alternate Suction port - G 3/4 BSP & ensure it to be air tight after filling). Connect a Hose pipe of suitable size to the air bleeding port - G 1/2 BSP. Now, switch on the motor & wait for some time till you get full / uninterrupted flow. As soon as you get the uninterrupted flow, switch off the motor & plug the Air Bleeding port. Now, run the pump for short period at no load. Adjust the system main pressure relief valve to a required value and start using the system. Case II: When the pump suction port height is less than 300 mm above oil level. The pump need not have a check valve as mentioned above. During commissioning the Air bleeding port should be kept open to tank by connecting a hose pipe. Now, repeat the steps 4 to 7 of case -I.
B] When the Casing Pump is mounted Vertically
	Case I: When the casing pump is immersed in oil. Make the connection for air bleeding as shown in fig. using the kit provided with the pump. Loosen the Casing air bleeding plug completely. Wait for some time for the oil to fill the pump casing. The plug may now be retighten. Now run the pump for short period at no load. Adjust the main pressure relief valve of the system at required value and start using the system.
	Case II: When the oil level is below the suction port (i.e up to a distance of 300mm. Maximum). Make the connection for air bleeding as shown in fig. using the kit provided with the pump. Fit a check valve with almost nil cracking pressure at the bottom of the suction pipe. ( Refer check valve model codes given below). Now fill the pump casing with oil. This can be done by providing a pipe connection to alternate suction port as shown. Now loosen the casing air bleeding plug completely & fill the casing till oil is seen coming out of casing air bleeding port. Tighten the casing air bleeding plug once the casing is filled. Also, plug the oil filling port & ensure it to be air tight. Now run the pump at no load for some time. Adjust the main pressure relief valve of the system at required value and start using the system.
Note:-- Priming is not required to be done every time you start the pump after short durations (a day or two) of non-operation.
