Pump

Connection: All cast iron construction; NPT
Sizes: Four drive configurations — SAE, air-cooled with pre-mounted gasoline engine, frame mount, and close-coupled electric motor drive
Best for: The staple irrigation pump. A rapid-action check valve stops backflow and holds prime in the suction line, so it re-primes fast after a shutdown and will pull 25 ft of suction lift. Body design gives easy service access. Berkeley have been irrigating the San Joaquin Valley since 1937

Pump

Connection: Close-coupled electric motor drive; cast iron
Best for: Motor and pump on one shaft — a shorter, simpler install than a frame-mounted set, for a fixed pump house where you are not moving it around

Pump

Best for: The high-head end of the Berkeley self-priming range, for systems needing more pressure than the standard B-Series delivers

Pump

Pump

Flow: 1 to 25 gpm
Pressure: Adjustable 15–150 psi
Connection: Dual threaded — 1" female NPT and 1¼" male NPT; two ½" side ports for pressure switch, gauge or relief valve; one ¾" bottom port for the pressure tank
Best for: Holds constant pressure by throttling the pump to match demand, instead of cycling it on and off. That means a small tank and no VFD — far less to go wrong and far cheaper than variable-speed. Inlet-to-outlet pressure difference must stay within 125 psi

Pump

Flow: 1–30 gpm or 3–50 gpm depending on model
Pressure: Preset 40, 50 or 60 psi (stainless version 50 or 60 psi only)
Best for: Preset rather than adjustable — you pick the pressure at order and it holds it, with nothing to drift or be tampered with. Stainless version for corrosive water

Pump

Flow: 1 to 50 gpm
Pressure: Adjustable 25–75 psi, or 50–120 psi build
Connection: 1¼" male and 1" female threads; also 1¼" female NPT
Best for: Double the flow of the CSV1A in the same idea — automatically adjusts pump output to match a varying demand. Two pressure bands to choose from
