the
VFDs provide the
capability of varying

Vertiflo Pump Company
a vertical pump. These motors offer a
cost-effective method of varying the
pump performance as desired while
conserving energy consumption.
The Series 800, for example, provide
heads to 230 ft and up to 3,000 gal/
min flowrates, and operate at temperatures
to 350°F and pit depths to
26 ft. These vertical, immersion sump
pumps have a semi open impeller,
external adjustment, and come standard
with NEMA C face motors (VFD
motors are optional). - Vertiflo Pump

An expanded line of
explosion-proof Roots pumps
Designed in accordance with the
ATEX Directive (2014/34/EU1 and/
or 1999/92/EC) with pressuresurge
resistance of PN 16, Roots
pumps from the OktaLine (photo)
meet the very highest explosionprotection
requirements. This series
of pumps is now expanded, with
pumping speeds ranging from 280
to 8,100 m3/h. With their magnetic
coupling, OktaLine pumps are hermetically
sealed and achieve extremely
low leak rates of 10-6 Pa
m3/s. Compared to pumps with
shaft seals, the OktaLine's magnetic
coupling achieves up to 20%
lower operating costs and considerably
reduced maintenance costs,
says the company. The magnetic
coupling eliminates the need for
shaft seals. OktaLine ATEX pumps
are pressure-surge resistant up
to 1,600 kPa. - Pfeiffer Vacuum
