Installation

General Information

DThe Typical Installations in Fig. 2 are only guides for selecting and installing system components. Contact your Graco distributor for assistance in planning a system to suit your needs.

DAlways use Genuine Graco Parts and Accessories.

DUse a compatible, liquid thread sealant on all male threads. Tighten all connections firmly to avoid air or fluid leaks.

Tightening Threaded Fasteners Before First Use

Before using the pump for the first time, check and retorque all external fasteners. See Torque Se- quence, page 29. After the first day of operation, retorque the fasteners. Although pump use varies, a general guideline is to retorque fasteners every two months.

Toxic Fluid Hazard

Read Toxic Fluid Hazard on page 3.

Use fluids and solvents that are compatible with the equipment wetted parts. Refer to the Technical Data section of all equipment manuals. Read the fluid and solvent manufacturer’s warnings.

CAUTION

Safe Operating Temperatures

Minimum (all pumps): 40_ F (4_ C) Maximum

Acetal: 180_ F (82_ C)

Polypropylene: 150_ F (66_ C)

Aluminum, stainless steel, PVDF: 225_ F (107_ C)

These temperatures are based upon mechanical stress only and may be significantly altered by pumping certain chemicals. Consult engineering guides for chemical com- patibilities and temperature limits, or contact your Graco distributor.

Mountings

DThese pumps can be used in a variety of installa- tions. Be sure the mounting surface can support the weight of the pump, hoses, and accessories, as well as the stress caused during operation.

DFig. 2 shows some installation examples. On all installations, mount the pump using screws and nuts.

Pumping High-Density Fluids

High density fluids may prevent the lighter non-metallic check valve balls from seating properly, which reduces pump performance significantly. Stainless steel balls should be used for such applications.

Split Manifolds

Plastic Split Manifold Kits are available to enable you to pump two fluids simultaneously or to mix two fluids in the pump. To order a Split Manifold Kit, use the Part No. from the list below:

241240 polypropylene; split inlet

241241 acetal; split inlet

241242 PVDF; split inlet

241243 polypropylene; split outlet

241244 acetal; split outlet

241245 PVDF; split outlet
