System is unassembled (for shipping purposes) and includes all necessary valves, tank, grades of media, underbedding, internal distributors/strainers, drain line flow controls, and the clock/timer/stager assembly mounted into a control box. External piping is not included. Customer may want to consider system additions of pressure gauges, sample cocks, vacuum breakers, flex connectors, bypass valves, shut-offs, etc.

Cast Iron Valve available connections: (FPT: 1.5 inch, 2 inch, 2.5 inch, 3 inch); (Flanged: 3 inch, 4 inch, 6 inch)

Plastic Valve available connections: (MPT: 1.5 inch); (Male Spigot Weld: 1.5 inch, 2 inch); (Female Socket Weld: 2 inch); (Flanged: 2 inch, 3 inch)

Recommended Service Flow Rates/Ranges are based on the sq.ft. of the tank/filter bed. Slower flow rate per sq.ft. = Better Filtration
— 5 to 10 gpm/sq.ft. = Superior filtration (20 to 40 micron nominal) with less than 5 to 10 psi pressure drop
— 10 to 15 gpm/sq.ft. = High quality filtration (40 to 100 micron nominal) with up to 10 to 20 psi pressure drop
— 15 to 20 gpm/sq.ft. = Utility filtration only (no micron rating estimate) with up to 25 to 30 psi pressure drop

System Flow Rates as listed are based on pressure drop curves of less than 2 psi drop through the service valves.

Backwash Rates for proper bed cleaning are best achieved at 20 to 25 gpm per sq.ft. However, allow backwash variations to as low as 15 gpm/sq.ft. for valve sizes, pipe sizes, pump sizes, water availability, and unique applications.

Backwash Rates allow up to 5 psi loss through the backwash valves.

Backwash Flow Restrictors are included and can be provided to accommodate any desired backwash flow rates.

Valve Sizes and Tank Size Pairings for special flow rates and backwash rates may be substituted at customer request or are application dependent.

Operating Pressure: 100 psi (7 bar)

Maximum Temperature: 140°F (60°C)
