7.4.2
Rinse Gland
This option provides for rinsing the rear portion of the piston with a liquid passing at a low flow rate through the annular
gland. This precludes migration of the metered liquid beyond this groove, preventing it from reaching the rear of the pump.
This also reduces the chance of the piston binding in the cylinder.
7.4.3
Cartridge Heater Ports/Cartridge Heaters
Optional cartridge heater ports and cartridge heaters are available. IVEK Corporation will assist the user in determining
the optimum heater specification. Pump head heating is used to maintain liquid temperature. Heating is not used to
increase liquid temperature.
7.4.3.1
Cartridge Heater Ports
Optional cartridge heater ports can be provided in the pump case to keep the Pump Module at an elevated temperature.
The 1/ 4" diameter ports are located in the pump case 180
O
apart.
7.4.3.2
Cartridge Heaters
Optional cartridge heaters can be mounted in the cartridge heater ports. A temperature controller and thermocouple may
also be provided. If a controller is provided, instructions for the controller are provided in Chapter 11.
7.4.4
Fittings
Fittings are available with the Pump Module. Chapter 9 lists the IVEK part numbers for the available fittings, associated
seals and sleeves when required. Not all fittings shown are applicable to the Split Case Pump Module.

MAINTENANCE
CAUTION
Never connect or disconnect the cable from the Motor/Base Module connector while power is on. Damage to the
equipment may result.
7.5.1
Preventative Maintenance
The ceramic components for the Pump Module have been designed to last for millions of repetitions without wear.
Preventative maintenance should include careful handling of the piston and cylinder when they have been removed from
the Pump Module. Always take great care when removing the piston from the cylinder and replacing the piston into the
cylinder. Never clean ceramic parts in such a way that they can vibrate against each other. This could cause chipping.
The piston and cylinder are a matched set and should always be kept together. Each piston and cylinder are identified
with a number which match the parts as a set.
CAUTION
Ceramic piston/cylinder sets are particularly sensitive to neglect and may “freeze” if allowed to dry out without
adequate cleaning.
7.5.1.1
General Applications; Routine Cleaning Procedure.
1. Disconnect inlet tubing from process liquid supply container.
2. Cycle pump in continuous mode until remaining process liquid has been purged from the Pump Module liquid path.
