VND series semi-submersible vertical motor pumps (high-head pumps)

High-head multi-stage pumps of the VND50/150…640 series are a new generation of semi-submersible centrifugal pumps for oil transportation and petroleum industry. The structural design of the pump rotor shaft is a between bearing system on roller bearings isolated from the handled medium by a system of double end face mechanical seals of the “Tandem” design. The condition of the barrier fluid can be visually controlled. These pumps can provide maximum operation periods while handling heavily contaminated petroleum products without the need to clean the filters.
