VT Series Vertical Turbine Pump

Line-shaft turbine pump for wet pits, river intakes and deep wells. The bowl assembly sits under the liquid level, so the pump never has to lift its own prime.

Bowl assembly under the liquid level: no priming, no suction lift

Column and bowl count made to the sump drawing, not to a stock length

Shaft-line critical speed calculated for every quoted column length

Non-reverse ratchet fitted as standard on hollow-shaft drives

Product detail

Where the suction sits well below the floor — an intake channel, a storm sump, a deep well — a vertical turbine removes the NPSH problem instead of managing it. The VT Series is built to the site’s sump drawing: column length, bowl count and discharge head are made to order rather than picked from three lengths.

Bowls are supplied in cast iron, bronze-fitted or all-stainless construction depending on the water. Line shafting runs in cutless rubber or bronze bearings, product lubricated as standard, with an enclosed oil-lubricated option for sandy water. The discharge head takes either a hollow-shaft vertical motor with a non-reverse ratchet or a right-angle gear drive for engine-driven installations.

Critical speed of the assembled shaft line is calculated for every column length we quote, because a column that resonates at running speed will destroy the bearings whatever the hydraulics do.
