Teflon Graphite (TG) plunger seal is a spring-loaded mechanical seal. Alternate O-ring plunger seal sets are available in Viton, Buna N, Kalrez and EPR. TG seals should only be used above 1000 psi. NOTE 2: PLUNGER (Item #9). Designate the proper plunger material by adding a dash number to the base base part number. For 17-4ph (A), for 316SS (B), and for ceramic (CR). LUBRICATION: All pumps are supplied with SF96-100 plunger seal lubricant. Use G321M4 U-cup silicone grease when rebuilding the pump. This is contained in a complete pump repair kit. REPAIR KITS: The items identified with the symbol are contained in a complete pump repair kit (See bulletin no. RK-P2250W600/800). Controller and relay repair kits must be ordered separately. IMPORTANT: Plunger seals (TG only) must be installed at an angle (see bulletin no 987.1). Pump Body Assembly must be ordered as a complete unit (item no. 16). RELAYS: The injectors model no. P2250W600S, P2250W600L and P2250W800S always require the relay model no. PO4-6S. RELAYS: The injector model no. P2250W800L always require the relay model no. PO4-8S. RELAYS: When using a relay it is recommended to use a pressure regulator (PCV) for the ”Oscillamatic” controller and another PCV for the relay. The pressure supply to the ”Oscillamatic” controller should be set at 35 PSI. RELAYS: The pressure supply to the relay should be a minimum of 50 PSI to a maximum of 150 PSI, depending on the required discharge pressure. TO BE CONSIDERED ONLY ON PUMPS INCLUDING AN 8 INCH PISTON: It is recommended to install a volume chamber or a supply line of a minimum size of 1/2 inch in size, between the PCV and the relay. This allows the necessary volume to the relay during maximum operating conditions. 201 Ivyland Road Ivyland, PA 18974-0577 USA • (215) 293-0415 • Toll Free in the USA (800) 235-3421 • Fax: (215) 293-0498 • E-mail: [email protected] PL-P2250W • Revised 12-99
