Casing
l Heavy duty, top centerline discharge casing with integral
cast feet provides maximum resistance to pipe loads for
improved seal and bearing life.
l Minimum 3mm corrosion allowance maximizes pump life
at corrosive and erosive applications.
l Back pull out design makes maintenance activities safe and
simple.
l Standard 3/8” NPT casing drain for safe maintenance.
l Renewable wear ring maintains pump performance during
full lifetime of pump (optional).
l Confined casing gasket provides safe pressure contain-
ment against gasket „blow out” and protects alignment fits
from corrosion for ease of maintenance.
Impeller
l Precision-cast enclosed impeller design provides maxi-
mum efficiency and optimum NPSH performance.
l Back vanes or balance holes reduce axial thrust and seal
chamber pressure for extended bearing and seal life.
l Key driven for maximum reliability, eliminates spin-offs
due to reverse rotation during start-up.
Engineered Shaft Sealing Environment
l Wide choice of sealing arrangements for maximum
sealing flexibility.
l Patented „cyclone” seal chamber improves lubrication,
cooling and solid handling for ultimate seal life.
Corresponding with to ISO 5199 and ISO 2858 for maximum reliability and easy installation.
Superior hydraulic design for maximum performance and extended mechancial reliability.
