SPX Corporation Rotary Pump R4RI

Pump discharge pressure tends to push the rubber cover gasket and plunger towards the front of the pump. This pressure compresses spring allowing pressure to be relieved by escaping via the rear side of the gasket and the recess of the outer cover. The venting pressure can be set by adjusting spring tension with the adjusting nut.

1. Place a pressure gauge in the downstream line close to the pump; between the pump and other downstream equipment.

2. Place a shut-o valve in the discharge line immediately downstream from the pressure gauge. Leave the valve wide open.

3. Loosen the lock nut and turn the adjusting nut clockwise as far as it will go. This is to prevent any venting during Step 4 below.

4. Pump product through system at the desired temperature and adjust the pump speed until the desired capacity is attained.

5. Check the pressure gauge for the desired pumping pressure. Example: 40 psig (2.8 kg/cm2).

6. Determine the venting pressure needed to protect the system. Example: 45 psig (3.15 kg/cm2). Venting pressure must always be higher than the pumping pressure.

7. Now turn the adjusting nut counterclockwise until only two or three threads are engaged.

Warning: Always lubricate parts after disassembly for cleaning or maintenance.

When processing food products, use a sanitary grade lubricant (approved for incidental contact with edible products) on all product contact surfaces during assembly.

Use high quality non-emulsifying gear oil.

Select the type of gear oil used

When processing food products, use a sanitary grade lubricant approved for incidental contact with edible products (USDA Classication H1) on all product contact surfaces after disassembly for cleaning or maintenance.

1. APV equipment is inspected prior to shipment. When leaving the factory, it is well crated for normal transportation procedures. APV cannot, however, guarantee safe arrival. Therefore, upon receipt of this equipment, check the received items against the packing list for damage or missing parts. Check the packing material thoroughly for small parts.

2. Visually inspect for damage or loss. Damage or loss should be reported immediately to the delivery carrier while present. Following the immediate notication of the lost or damaged parts, a detailed description including quantity, description of the loss or damage, and a cash value should be claimed against the carrier with respect to the guidelines set forth by the responsible carrier’s policies.

APV’s responsibility terminates F.O.B point of manufacture unless otherwise specied per the General Terms and Conditions of Sale as published by APV and amended from time to time. Contact APV Order Services if shipping information is required for handling claims.

3. In the case of damage or loss to the equipment, APV may perform three major functions:

a. Manufacturer Function – APV manufactures quality equipment and stands behind the APV Standard Warranty. Refer to the Standard Warranty.

b. Assessor Function – APV oers assessment services for ling claims. The APV assessor will accurately determine the extent of the damage (or loss) and cost of repairs to the equipment. Reimbursement for this service will be agreed upon prior to the assessment.

c. Repair House Function – APV oers services for repairing the damage(s) or replacement of loss(es) to the equipment. APV has the option to alter the Standard Warranty on refurbished or replacement parts. The cost of this service will be dependent upon the assessment that is made.;
