"Camel" Liquid Ring Medical Vacuum
A.6 Maintenance
A.6.1

Introduction

One of the main features of the "Delta" EC pump is its simple design, great sturdiness and requirement of minimum
maintenance. In order to avoid inconvenience and trouble, the operators should be reminded that:
The pump should not be operated without service liquid. Damage to the mechanical seal will result. Solid
impurities are to be retained by a filter. If the service liquid is water, it is necessary to control its hardness. If the
water has a high salt content, the scale deposits resulting will increase the power absorbed by the motor and will
wear the pump parts. It is necessary to remove the scale deposits, and clean the pump frequently. The main
maintenance operations that may be necessary are:
- Replacement of the mechanical seal.
- Replacement of the valves.
- Internal cleaning of the pump.
- Replacement of the bearings (see table below for sizes).
If maintenance operations involve disassembly and re-assembly, please follow the directions in Section A.5.

Bearing Lubrication

The "Delta" EC pumps are fitted with airtight, pre-lubricated bearings. No bearing lubrication is required. Under
normal operating conditions, it is recommended that the bearings be replaced after approximately 20,000 working
hours. See the table below for the bearing sizes of the various size pumps.
