Pumps by manufacturer

Berkeley

B-Series Self-Priming Centrifugal Pumps

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

B-Series Close-Coupled Centrifugal Pumps

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

LTHH Series Self-Priming Centrifugal Pumps

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

Cycle Stop Valves

CSV125 Thermoplastic

Pump
Sizes
CSV125-1 and CSV125-3
Best for
Thermoplastic body for water that would attack a metal valve

CSV1A

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

CSV125 / CSVS125

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

CSV2W

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

Munro

LP Series 3/4 – 3 HP

Pump
Flow
At 5 ft suction lift: ¾ HP 63 gpm @ 20 psi · 1 HP 73 gpm @ 20 psi · 1½ HP 75 gpm @ 20 psi · 2 HP 102 gpm @ 20 psi · 3 HP 115 gpm @ 20 psi (still 100 gpm @ 40 psi)
Pressure
Shut-off 45–61 psi by model; maximum case pressure 150 psi
Connection
2" threaded suction, 1½" threaded discharge. Two ¾" FPT priming and accessory ports (one takes a pressure sensor and gauge) plus a ¼" FPT port for a temperature sensor — which is how a SmartBox is plumbed to it
Sizes
Five models — LP075B (¾ HP), LP100B (1 HP), LP150B (1½ HP), LP200B (2 HP), LP300B (3 HP). Motor is ODP, single or three phase, 60 Hz, 115/208/230/460 V, class B or F insulation
Best for
The workhorse turf and nursery pump — drawing from ponds, lakes, streams, cisterns and shallow wells, or boosting domestic pressure for irrigation. Cast iron body, mounting ring and diffuser, a machined and balanced brass impeller, stainless steel wear ring and a carbon-ceramic seal — where many competing turf pumps are plastic. Maximum suction lift 15 ft, though Munro recommend keeping total suction lift under 10 ft for best performance

LP 1502

Pump
Flow
At 5 ft suction lift: 75 gpm @ 40 psi · 67 gpm @ 50 psi · 56 gpm @ 60 psi · 38 gpm @ 70 psi
Pressure
Shut-off 80 psi; maximum case pressure 100 psi
Connection
2" threaded suction, 1½" threaded discharge
Sizes
2 HP — LP1502B (single phase) and LP1502B3 (three phase)
Best for
Multi-stage pressure out of a single impeller. Where you would normally reach for a multi-stage or a 5 HP pump to get 60 psi at useful flow, this 2 HP unit does it with one brass impeller — a shorter shaft, less bearing load, and none of the alignment and wear problems extra stages bring. Maximum suction lift 15 ft

LP 3005

Pump
Flow
At 5 ft suction lift, LP3005B: 145 gpm @ 30 psi · 132 gpm @ 40 psi · 110 gpm @ 50 psi · 85 gpm @ 60 psi · 47 gpm @ 70 psi. LP3005B3: 120 gpm @ 45 psi · 98 gpm @ 55 psi
Pressure
Shut-off 75 psi; maximum case pressure 100 psi
Connection
3" threaded suction, 3" threaded discharge
Sizes
5 HP — LP3005B (single phase) and LP3005B3 (three phase)
Best for
The mid-size block — athletic fields, small pastureland, or a nursery needing more flow than the 3 HP LP will give. Brass impeller, stainless wear ring, heavy-duty motor. Note the LP3005B uses a keyed shaft and sleeve, so impeller removal at service time can need heat. Maximum suction lift 15 ft

BP Series

Pump
Pressure
Case pressure to 175 psi
Connection
Dual connection — threaded and grooved
Sizes
5 HP
Best for
The high-pressure end of the Munro range — a straight (not self-priming) centrifugal, where the 175 psi case rating lets it work as a serious booster. Two connection styles on the same pump, so it drops into threaded or grooved pipe without adapters. Small footprint makes it a common pump-station choice

MU Series 7½ – 20 HP

Pump
Sizes
7½ to 20 HP
Best for
The top of the Munro self-priming range, for blocks needing greater flow and higher head than the LP series delivers. The enclosed one-piece bronze impeller is balanced and trimmed to a specific operating range, so the duty point matters more than the horsepower when specifying one. Mechanical shaft seal and heavy-duty motor

RP Series

Pump
Connection
3" threaded discharge; solids handling to 0.31"
Sizes
½ HP to 5 HP. Enclosed channel chrome steel impeller on 2–5 HP, open vein impeller on ½–1 HP. Example model RP0302S22 — 2 HP, 230 V single phase, 9 A, about 21" long. A separate RP LV sub-series covers 7½–20 HP
Best for
Low head, high flow, running continuously — recirculating water features, non-potable water transfer and flood irrigation. Installs vertically or horizontally, which matters when the pump has to be concealed inside a decorative feature. The flow path runs across the motor housing to carry heat away and amp draw is low, which is what makes continuous duty affordable to run. Stainless steel outer case, thermally protected motor, double mechanical shaft seal (carbon/ceramic upper, silicon/silicon lower), steel suction strainer, sealed cable entry and a lift ring

FS Series 1/3 – 30 HP

Pump
Connection
3" NPT threaded discharge on the 2 HP model; solids handling to 0.36"
Sizes
⅓ HP to 30 HP. Abrasion-resistant high chrome steel impeller on 2 HP and above, balanced ductile iron impeller on ⅓–1½ HP. Example model FS315S11 — 2 HP, 110 V single phase, 20 A, about 22" long
Best for
Dewatering and water transfer across a very wide horsepower band. A stainless steel double casing takes the flow across the motor housing for continuous running, with a heat-treated stainless shaft, thermally protected motor, double mechanical seal (carbon/ceramic upper, silicon/carbide lower), stainless suction strainer, sealed cable entry and a lift ring. Built tough enough for mine and construction dewatering, which is why it holds up easily on irrigation duty

Complete PRO II 3/4 – 3 HP

Pump
Connection
2" suction and 1½" discharge on the pump; cam-lock quick-connect fittings both sides, with a flexible rubber discharge hose rated to 150 psi working pressure and a 1½" PVC solvent-weld × cam-lock transition to the mainline. AWG 12/3 pigtail prewired to the motor for the provided electrical outlet
Sizes
¾ HP to 3 HP, built on the LP series pump and controlled by a SmartBox
Best for
The whole pump station in one part number — professional-grade pump, SmartBox control with built-in protection, simplified plumbing and a purpose-built enclosure. It exists because hand-built pump houses are where the fittings, gauges, wiring and code violations creep in. Ships complete and carries a 2-year comprehensive warranty rather than the usual 1 year

Complete PRO II – On Demand

Pump
Best for
The Complete PRO II fitted with the Pressure Start Control Box instead of a controller input — open a hose or a spigot and the pump starts on demand, with no lawn controller and no pressure tank. It uses flow and pressure together to detect demand. The obvious answer for a dock, a wash-down point or spot watering off a pond, lake, stream, cistern or shallow well. 2-year warranty

Complete PRO II 5 HP

Pump
Sizes
5 HP — skid-only, or with a powder-coated marine-grade aluminium enclosure
Best for
The 5 HP Complete PRO II, with the enclosure made optional. Take the skid for an indoor pump room where you only need the assembly done properly; take the marine-grade aluminium enclosure where it has to stand up outdoors

Complete BOOST

Pump
Best for
For an existing irrigation system that has lost pressure — an expanding neighbourhood, over-taxed domestic supply, pop-ups that will not pop. It plumbs into the system and adds pressure automatically whenever flow goes above 5 gpm, so it stays out of the way the rest of the time. Stainless steel pump, self-contained, plug-and-go

Universal PRO Pump Enclosure

Pump
Sizes
Accommodates pumps up to 3 HP
Best for
A proper enclosure for a pump you already own — powder-coated stainless steel, with inlet and outlet ventilation, mounting for a pump control box, and security features. Rot-free, maintenance-free and vandal resistant, which a site-built plywood box is not. Ships flat and assembles with a hand rivet gun
