VEVOR 1HP Stainless Steel Sump Pump: features, specs and who it suits

The VEVOR 1HP submersible pump (model FSP27DWS-900) is built to move water out of a sump pit, flooded basement, pond or similar low spot. It has a stainless steel body, an automatic float switch and an inlet sized for dirty water that carries small solids. This page explains what the figures mean and what to confirm for your own setup.

Flow rate and lift

VEVOR rates the pump at a maximum flow of 4020 gallons per hour, or 67 gallons per minute, with a maximum lift of 30 feet. Flow and lift trade off against each other. The maximum flow figure applies at low lift, and the amount of water delivered falls as the water has to be pushed higher or through longer, narrower hose. If your discharge point is well above the pit, the real output will be lower than the headline figure.

The motor is a 1HP copper-wound motor. The listing says a wider outlet gives higher flow rates, which is why it comes with several connectors.

Handling dirty water

The large bottom inlet passes particles and debris up to 1.38 inches (about 3.5 cm) in diameter, according to VEVOR. That makes it suited to muddy or silty water and liquids with small solids. Heavier sludge and larger debris can still clog any pump, and a pit with a lot of grit may need regular cleaning.

Build and waterproofing

The shell and base are 304 stainless steel, a grade chosen for corrosion resistance. VEVOR lists it as IPX8, meaning the pump is designed to be submerged continuously, and describes an integrated design with a mechanical seal. The pump is 7.5 x 6.3 x 14.2 inches and weighs 11.8 lb.

Automatic float switch

A mechanical float switch turns the pump on and off with the water level. VEVOR says it starts when the level reaches 20 inches and stops when it falls to 6 inches. Pits and tanks need enough depth for that range, and the float needs room to move freely so it doesn't snag on the wall or pipe.

Before first use, VEVOR says to tilt the pump and submerge it for a few seconds to let air escape. It also warns not to lift the pump by its power cord, which can permanently damage it. The cord is 26 feet long.

Hose connectors

The pump comes with connectors for a range of hoses:

• NPT 3/4" and NPT 1" connectors for standard garden hoses
• A 1.5" male thread connector for heavy-duty, higher-flow jobs
• A multi-purpose connector with three outlet diameters (1", G1" and 1.5")

Who it suits

It suits homeowners who need to clear a sump pit or a flooded basement, and people draining a pool, pond, hot tub or garden water feature. It is a drainage pump for clean and dirty water, not a pump for supplying drinking water.

What to check before you buy

• Power supply: check the electrical requirements in the manual, and use a properly grounded outlet that meets local electrical codes.
• Pit size: confirm that the pit is deep enough for the float's 6 to 20 inch range.
• Discharge height and distance: estimate how high and how far the water must travel, and match the hose.
• Check valve and hose: many installations use a check valve to stop water flowing back. Check what the manual advises.
• Solids: make sure typical debris in your pit is below 1.38 inches.
• Upkeep: inspect the inlet and float from time to time.
