Installation - Rotary Pumps
Your PROCON® pump is a precision-built piece of equipment. Handle it carefully. PROCON® pumps should be installed only by qualified technicians.
When you install your pump, follow these guidelines:
- We test every PROCON® pump at the factory for pressure and flow. If the pump has a relief valve, we set it to your specifications.
Do not tamper with the relief valve on your pump. If you think the relief valve needs to be reset, contact your PROCON factory representative.
We make every effort to ensure that your pump is of the highest quality. To get the most out of your pump, read and follow these instructions carefully.
You should have these parts:
- Bolt-on PROCON® ROTARY VANE PUMP
- Pump motor adapter
- 3-piece drive shaft coupling
- 56C frame motor
Correctly assembling the coupling and the adapter, and mounting the pump is a trial and error process. You may have to try several times before you get it right. Follow these steps after you have examined your pump.
- Mount the drive shaft coupling.
a. Make sure motor is electrically disconnected and cannot accidentally turn on.
b. Mount the half of the coupling for the motor onto the motor shaft and tighten the set screw.
c. Insert the elastomer piece onto the motor piece.
d. Mount the half of the coupling for the pump onto the pump shaft, but do not tighten the set screw.
Make sure the coupling slides easily onto the pump and the motor shaft -- do not force it. Make sure the shaft does not protrude into the space occupied by the elastomer piece. Series 6 pumps require a shaft key.
- Mount the motor adapter onto the motor using four 3/8 inch dia. by 1 inch long bolts (16 threads/inch) and lock washers. Rotate the pump to orient the inlet/outlet ports as desired.
- Trial mount the pump onto the motor adapter while simultaneously engaging the coupling pieces.
- Check to make sure that the coupling is properly engaged.
- Tighten the set screw on the pump coupling half.
- Check your assembly.
The elastomer coupling piece should have about 1/16 inch of play between the two metal pieces.
If it does, go to step 7.
If it does not, repeat steps 1 through 5, until the assembly is correct.
- Fasten the pump to the adapter using three 1/4 inch dia. by 3/4 inch bolts (20 threads/inch) and lock washers. For Series 6 pumps, use two 3/8 inch dia. by 1 inch bolts (16 threads/inch).
- Check to make sure that your motor rotates correctly. Motor rotation must correspond to the rotation arrow on the nameplate of the pump.
You should have these parts:
- Clamp-on PROCON® pump
- PROCON V-band clamp
- 48YZ frame motor
After you have examined your pump for damage, follow these steps.
- Make sure motor is electrically disconnected and cannot accidentally turn on.
- Slip the V-band onto the motor ring flange.
- Mount the pump to the motor by inserting the tang (shaft) of the pump into the slot on the motor.
- Rotate the pump to orient the inlet/outlet ports as desired.
- Make sure the ring flanges on the pump and on the motor are properly engaged and flush against one another.
- Make sure the clamp is fully seated around the entire circumference of the pump and motor flanges.
- Tighten the V-band clamp using 15 to 30 inch-pounds of torque.
Note: Do not over tighten the clamp. The V-band clamp is designed to support the pump and fittings only. Loads caused by rigid plumbing or heavy attachments may result in misalignment.
When you finish mounting your pump on a motor, you must install the plumbing for the pump. Follow these steps after you have mounted your pump.
1. Install the inlet and outlet fittings.
- Support the pump by using a backup wrench on the square port bosses. Do not put any strain on the V-band clamp.
- Use brass fittings or plastic fittings on a brass pump. Use stainless steel or plastic fittings on a stainless steel pump. Using dissimilar metals can cause corrosion, which may get into the pump and cause damage.
- Use Teflon thread tape to install the fittings. Do not let any thread tape get into the pump and do not over-tighten the fittings.
2. Check the inlet line.
- Make sure that the inlet line is big enough to allow adequate flow to the inlet port of the pump (3/8 inch internal diameter for Series 1, 2, & 3 ; 1/2 inch internal diameter for Series 4 & 5; 1 inch internal diameter for the Series 6; all elevated temperature applications above 65°F must have oversized inlet piping).
- Make sure that the inlet line is clean and properly flushed out. Protect the pump with a 100 mesh or finer strainer or filter.
3. Connect the inlet line to the fitting on the pump.
4. Connect the outlet line to the fitting on the pump.
