Our take on the Berkeley B3TPMS Close-Coupled Centrifugal Pump 1.5 HP

The Berkeley B3TPMS is a close-coupled centrifugal pump with a 1.5 HP three-phase motor turning at 1800 RPM. It has a 4-inch flanged suction and 3-inch flanged discharge, so it moves high volumes at low head rather than high pressure. It suits irrigation, water transfer and booster duty where a three-phase supply is available. Compared with smaller single-phase pumps it handles more flow and runs cooler at 1800 RPM, but it needs a starter and three-phase power, and it is not a self-priming unit.

Pros
  • Large 4-inch suction and 3-inch discharge for high flow
  • 1800 RPM motor runs quieter and wears less than 3600 RPM units
  • Three-phase motor is efficient and long-lived
  • Close-coupled design saves floor space and alignment work
  • Simple centrifugal build with few parts to service
Cons
  • Requires three-phase power and a starter, not a plug-in pump
  • Not self-priming; needs a flooded suction or foot valve
  • 1.5 HP gives flow, not high pressure, so tall lifts are limited
  • Flanged connections need matching pipework

Questions and answers

What is a close-coupled centrifugal pump?
The pump impeller mounts directly on the motor shaft with no separate bearing frame or coupling. That makes the unit compact and avoids shaft alignment, but the motor bearings carry the pump load.
Will it work on single-phase power?
No. The motor is three phase, so it needs a three-phase supply and a suitable starter or contactor. It will not run from a standard household single-phase circuit.
Does it prime itself?
No. It is a standard centrifugal pump and must have water at the suction, either from a flooded inlet or a foot valve. Running dry will damage the seal.
What flow and pressure can 1.5 HP at 1800 RPM deliver?
Expect high flow at modest head, in the range suited to irrigation and transfer rather than deep wells. Check the published pump curve for the exact flow at your required head before sizing pipework.
What pipe sizes does it take?
A 4-inch flanged suction and a 3-inch flanged discharge. You will need matching flanges and gaskets; reducing the suction line will cut flow.
Is it suitable for boosting household water pressure?
It can boost pressure on a three-phase system, but it is sized for larger flows than a single home needs. For a house, a smaller booster pump is usually the better fit.
Where is the Berkeley B3TPMS Close-Coupled Centrifugal Pump 1.5 HP cheapest?
At ePumps, for $3,146.40, as of our latest check.
