DESIGN BENEFITS
Seize-Proof
Unlike conventional centrifugal pumps, the
Roto-Jet pump will not seize if run dry by a loss
of suction or if operated with a minimal
continuous bypass flow against a closed
discharge valve. The mechanical seal is not
mounted to the pump drive shaft, therefore, seal
failure temperature rise is not transferred to the
critical drive shaft/bearing area. The Roto-Jet
design does not incorporate wear rings or any
close shaft tolerances which would be subject to
heat expansion and drive shaft seizure.
Performance Flexibility
Any given model is capable of higher or lower
pressure performance by simply changing the
external pump speed and applying the required
horsepower. No modification of the
pump is required. A wide range of
flow capability is achieved by
simply changing
the pitot tube.
Operation
The Roto-Jet is totally, hydraulically stable and
can operate with a minimal continuous bypass
flow at shutoff indefinitely and at any flow point
throughout the total head curve rang with no
wearing or damaging effect to the pump. The
reason for this unique benefit is that all radial
forces tend to be balanced within the rotor, and
axial thrust is solely a function of suction
pressure. Radial and axial forces applied to the
Roto-Jet are independent of flow rate. Thus, the
pump can operate at design point to shut-off
free of shaft deflection or added thrust load
applied to the bearings
Design Simplicity
A single stage pump with only two basic
working parts; (1) a rotating case and (2) a
stationary pitot tube. The pump has only one
wearing, rubbing part and that is a
mechanical seal that sees only
suction pressure. Seal leakage due
to seal failure vents to atmosphere.
Seal leakage cannot
contaminate bearing area
due to isolation of the
bearing pedestal
from the wetted
end of the pump.
For this reason, the Roto-
Jet can be kept in service
with a damaged seal to meet the
critical demands of daily
production.
