INDUSTRIAL COOLING. ENGINEERED TO PERFORM.
Process Cooling Systems high‑efficiency media filters are configured for either manual or automatic backwashing of the filter bed and are self‑contained to provide efficient particulate filtration on systems with high particulate loading.
Each filter includes a pump, motor, basket strainer, backwash valves, filter vessel and required controls for either manual or automatic backwashing of the filter bed. All components are rated for outdoor use, are factory assembled with interconnecting piping, and include UL-certified electrical. Standard filters are configured for process water backwash but are available configured with city water backwash.
BASE:
High‑density polyethylene pallet with four‑way access, 3.5″ fork slots, and grated top.
PUMP:
Self‑priming pump complete with brass volute, pump shaft, and open‑faced bronze impeller. Pump will be close-coupled to a TEFC motor.
MOTOR:
TEFC, NEMA 56 industrial frame motor. This motor offers consistent power to promote superior water circulation and filtration, safety feature protecting unit from overload, and a standard dry end seal to minimize seal burnout and provide for easy maintenance. UL recognized, CSA certified, 3‑year warranty.
STRAINER:
5″ brass strainer with 2″ NPT connection point. Unit will come complete with a 5″ pump basket, brass pump inlet plug, and bronze tee handles with stainless steel studs.
FACE PIPING:
Manual Backwash: Brass piping assembly, complete with manual 3‑way bronze body ball valve and PVC piping (schedule 80). The 3‑way valve is connected together with a mechanical handle and a common outlet backwash pipe assembly.
Automatic Backwash: Brass piping assembly complete with automatic 3‑way forged brass body valve actuated by a NEMA 4–rated electric actuator. Filter inlet and filter vessel outlet are connected with schedule 80 PVC pipe assembly. Automatic backwash includes a 24 VDC, 2‑way solenoid valve assembly; inlet piping with pressure gauges; and NEMA 4 fittings with fail‑safe actuator. Accepts 24 VAC and 120 VAC.
Valves:
Manual Backwash: 3‑way manual bronze body ball valve with PFE seats. Valve is connected together with a mechanical handle and a common actuated inlet and outlet backwash pipe assembly.
Automatic Backwash: 3‑way forged brass body ball valve actuated by an electric actuator. Filter inlet and vessel outlet are connected with PVC pipe assembly. Includes 24 VDC valve and solenoid, accepts 24–240 VAC, and has NEMA 4 rating with fail‑safe actuator.
filter vessel:
Filter vessel, consisting of an inner shell of fiberglass‑reinforced polyester resin wound over with fiberglass roving.
The unit features an inflow diffuser, an even distribution of the water flow across the filter bed, and hydraulically balanced PVC internal laterals to maximize water flow and filtration.
The filter vessel is fitted with a manual drain fitting, large filter base for stable floor mounting, and a manual pressure relief valve. The filter vessel is rated for 50 psi maximum allowable working pressure.
