TONKAFLO SERVICE POLICY - LIQUID END

Section 6.0 (Tonkaflo Field Maintenance) in the Tonkaflo Installation, Operation, and
Maintenance Manual was written to assist our customers in performing minor maintenance
in the field on Tonkaflo pumps. Proper maintenance will ensure longer pump life and
minimize downtime. Tonkaflo pumps are manufactured to make field repairs on the
mechanical seal a quick and easy process. Bearing frame overhauls may be done by the
customer, a local maintenance shop, or the factory. If repair at the factory is desired, call GE
for a Return Goods Authorization (RGA) number (Section 8.0, Tonkaflo Pump Return
Authorization Procedure) and send the complete pump, with or without motor, to the factory.
For motor problems, such as worn out motor bearings, it is recommended that maintenance
be done at a local motor repair shop.
For Motor Service: Motors must be sent to the nearest authorized motor service center for
repair, replacement, and warranty disposition.
Field service of the liquid end, with the exception of mechanical seal replacement, is not
recommended. If a liquid end is damaged by running the pump dry, inadequate flow,
excessive deadheading, cavitation, or other reasons, contact a Tonkaflo distributor certified
for service or return it with or without motor to the factory for repair.
The pump has a oil lubricated bearing frame attached to the pump liquid end. It is typically
characterized by an "E" in the model number (e.g., SS5518E).
To return an oil lubricated bearing frame pump to the factory, GE requires the whole unit
(pump liquid end and bearing frame) less the motor, bedplate, and flexible coupling pieces.
The original bearing frame is essential for rebuilding the pump liquid end on 5500, 8500,
12500, 23000, and 24000 Series pumps based on the pump design (shimmed impellers). Also,
a bearing frame is required to test the pump. If we attach a new bearing frame to your pump.
If we attach a new bearing frame to your pump liquid end in order to test it, it will be shipped
with the repaired liquid end of the pump and you will be billed for it.
