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
3.5 to 7 gpm/sq.ft. = Superior filtration (5 to 20 micron nominal) with less than 5 to 10 psi pressure drop
7 to 15 gpm/sq.ft. = High quality filtration (20 to 50 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 10 to 15 gpm per sq.ft. However, valve sizes, pipe sizes, pump sizes, water availability, and unique applications, allow backwash variation to as low as 8 gpm/sq.ft.

Backwash Rates allow up to 25 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)

Suggested Application Flow Rates:
RO Pretreatment: 3.5 to 7 gpm/sq.ft.
Drinking Water and Process: 8 to 12 gpm/sq.ft.
Swimming Pool: 15 to 20 gpm/sq.ft.
