PROBLEM GUIDE

Piston Frozen In The Cylinder

If the piston gets frozen in the cylinder perform the following steps.
DO NOT TRY TO FORCE THE PISTON FREE!
Damage to the piston/cylinder set may occur.
1. Carefully remove the Pump Module from the Motor/Base Module. Remove the piston and cylinder from the split
case then soak in a compatible solvent.
2. If the Pump Module is not conveniently removable, the tube loop described in section 7.5.2.3 of this chapter may
permit solvent to dissolve the "frozen" residue in reasonable time.
3. If the aforementioned procedures fail, contact IVEK for technical help. It may be necessary to ship the Pump Module back
to the factory. Provide a note describing, in detail, what conditions caused the seizure and what liquids are being pumped.
It may also be necessary to return the Controller and Motor/Base Modules along with the Pump Module should
readjustment of the pump drive components be required to free the pump.
Table 7.2 contains a list of possible problems, causes and solutions for the Pump Module.
