Dayton 4JMV7 Centrifugal Pump 1 hp 90 gpm 304 Stainless Steel

SKU CH-BBTB-VJ5YE MPN 4JMV7

Centrifugal pump delivers up to 90 gpm flow at 65 ft head with 1 hp motor and 304 stainless steel housing

  • TypeDrain Components
  • Delivers up to 90 gpm for high-volume transfer
  • 1 hp motor provides strong pumping power
  • 304 stainless steel housing resists corrosion
  • 65 ft maximum head handles elevation demands
  • 75 gpm at 10 ft head for efficient operation

Pump Purpose

The Dayton 4JMV7 is a single-phase centrifugal pump built for moving clean water in commercial and light-industrial plumbing systems. Its 304 stainless-steel housing and closed impeller suit installers who need corrosion-resistant construction for continuous duty.

Capacity Limits

Maximum flow reaches 90 gpm at open discharge and 75 gpm at 10 ft of head, while shut-off pressure tops out at 150 psi and total head at 65 ft. Viscosity is limited to 31 SUS and media temperature to 200 Degrees F, so the unit is not suited for thick fluids or high-temperature process loops.

Build and Connections

The pump housing and impeller are both 304 stainless steel, with a 1 1/2 in NPT intake and a 1 1/4 in NPT discharge. These pipe sizes and the single-phase motor determine the piping layout and electrical supply required for day-to-day operation.

Questions about this item

Will the 1 1/4 in NPT discharge on this pump mate with the 1 1/4 in NPT fittings on my existing pipework?

Yes — both the discharge and the 1 1/2 in NPT intake use standard NPT threads, so they connect directly to matching NPT piping without adapters.

How can I verify the pump is delivering its rated 90 gpm once installed?

Measure the flow at the discharge; at 10 ft of head the pump should produce about 75 gpm, rising toward 90 gpm as head drops toward zero.

Does the 4JMV7 come with a power cord or starter, or must I supply those separately?

The pump ships as the bare centrifugal unit — motor, 304 stainless housing and closed impeller — so wiring, overload protection and any conduit are sourced separately.
