www.Webtrol.comJanuary 2017 1

This series of vertical multistage booster pumps offertechnically advanced designs to meet marketdemands including hot water applications.

Every NV Series pump goes through our rigorousquality assurance program, guaranteeing the pumpperformance and giving our customers peace of mind.

Features / BenefitsIn-line, space saving design, with suctionand discharge on the same plane allowingpump to be installed easily in linear pipingsystems.

Reliable, robust and maintenance free car-tridge type mechanical seals are standard.

Available in various sizes and materials, theNV Series pump is an excellent choice forindustrial and commercial applications.

All wetted parts are constructed of highquality stainless steel. Available in 304 or316 stainless steel.

Pump base(s) and flange size(s) allow it tobe a drop in replacement for similar com-petitors models.

Avaliable with ODP, TEFC as well as spe-ciality enclosures.
