For harsh liquids
July 1st 2010 Seal-less design enables Wanner's
Hydra-Cell pumps to handle most
liquids over pressures ranging from
very low to 70 bar and above. Some
models are rated to 170 bar.
The pumped medium is isolated
from the drive mechanism and 100%
contained within the wetted end of
the pump. There are no seals to wear
and heat is not a factor unless the
liquid is exceptionally hot. For some
installations Wanner recommends an
oil cooler to hold the viscosity of
lubricant in the drive end of the
pump within prescribed limits.
Oil coolers for use with Hydra-
Cell pumps are offered by the
company, enabling pumps to handle
liquids at temperatures to 120°C. More articles from Wanner International Ltd: |
