Chapter 4: Maintenance

Chapter 4 provides user maintenance procedures organized by system component. Component
categories include the hydraulic power system, hydraulic filters, switches, piston seal, hydraulic
drive, hydraulic cylinder, tie-rods, check valves, and coned and threaded connections. A filter
service schedule and hydraulic oil service schedule are included as well as procedures for making
hydraulic adjustments.

•

All stainless steel threaded connections should be lubricated. MFIC recommends Never-
Seez food grade compound, Bostik NSWT.

•

Always make sure that the system pressure is relieved before servicing.

•

Never tighten fittings while under pressure.

Replacing Piston Seal Assembly

Replace the piston seal when there is excessive product discharge from the drain hole in the
isolator. To access the piston seal, first remove the liquid end body from the isolator by carefully
following the procedure below. The seal, back-up rings and bearing should be replaced as an
assembly.

NOTE:

Refer to the Liquid End Pump Assembly Drawing #801.00429 on the CD.

Removing the Liquid End Body

1.

Operate the unit in Jog mode and extend the hydraulic cylinder piston fully (it may be
necessary to retract it about 1/8” from the extended position to complete step 8) so that
you will later be able to access the set screws (24) through the access holes in the isolator
(3).

2.

Disconnect the power supply.

3.

Position the LV1 such that the front of the machine overhangs the table top. This will
allow the liquid end body (4) to pass easily after disconnection.

4.

Disconnect any liquid quench tubing, if applicable.

5.

Remove the reservoir inlet/syringe from the check valve body by rotating the syringe
counterclockwise to unhitch the luer fitting connection.

6.

Remove the interaction chamber and any related tubing.

7.

Using the adjustable wrench provided, loosen the glands and remove the process piping
directly connected to the liquid end body and the isolator.

8.

Locate the two access holes on the isolator, one at 9 o’clock and the other at 3 o’clock on
the left and right side of the isolators (if the user is facing the front of the LV1). Refer to
Figure 4.1.
