Disposal of waste

Before any dismantling operation, make sure that the pump does not present any risk generated by
substances sucked in.
 See safety data sheet on ANNEX.
The pump must be dismantled. Materials must be sorted, collected and recycled in accordance with local
and national safety and environmental regulations.
The main wastes to be recovered are:
Metallic materials
DEEE
Oil
Collection and recovery must be carried out by approved service providers in accordance with the
regulations in force in the country.

TROUBLESHOOTING ADVICE IN CASE OF MALFUNCTIONING

Do not dismantle the pump more than necessary during repair, servicing or maintenance operations.
INCIDENT
1 - The motor cuts out.
1.1. Mains power supply voltage or frequency incompatible with motor characteristics.
1.2. Check the circuit breaker setting.
1.3. Check the electrical connections.
1.4. The oil is too viscous or the room temperature is too low.
1.5. Rise of pressure in the exhaust unit:
- oil separating cartridge clogged,
- pump exhaust line restricted or blocked.
1.6. Hard spot felt when pump rotated by hand: check the vanes.
2 – The pump flow rate is
2.1. Pump inappropriate for the application.
too low.
2.2. Suction intake screen clogged
2.3. Suction filter (optional) clogged
2.4. Oil separating cartridge clogged.
2.5. Piping too long or diameter too small, causing excessive head loss.
3 – Insufficient vacuum
3.1 Leaks in the vacuum pipes or monitoring and control gear.
created.
3.2 Insufficient lubrication: add oil; or filter clogged.
3.3 Pump too hot.
3.4 Air being taken in at automatic trap (impurities, etc.).
4 – Vacuum pump
4.1 Room too small, poorly ventilated or room temperature is too high.
overheating.
4.2 Insufficient distance between the wall and the pump fan.
4.3 Unsuitable oil.
4.4 Temperature of sucked in gas is too high.
4.5 Start of clogging of the separating filter.
4.6 Exhaust line cross-sectional area too small.
4.7 Poor lubrication: add oil; or oil filter clogged.
4.8 Clean oil cooler (only E200.R / E300.R / E350.R / E400.R / E500.R / E600.R)

PROBABLE CAUSE
INCIDENT
5 – Vacuum pump emits
5.1 Separating cartridge incorrectly installed.
fumes at exhaust, or oil
5.2 Separating cartridge broken or burst.
consumption is high.
5.3 Automatic trap for re-injecting oil is blocked or its float is filled with oil.
5.4 Oil filler cap not properly tightened.
5.5 Vacuum pump overheating.
5.6 Unsuitable oil.
6 – Oil backs up by suction
6.1 Non-return valve faulty.
to vacuum chamber
6.2 Motor running in reverse
7 – Abnormal noises
7.1 Pump makes clicking noise: vanes worn or deformed.
7.2 Metallic noises: fan is touching another part or the cover is touching a lubrication pipe.
7.3 Oil viscosity too high or oil too cold.
8 – Presence of water in
8.1 Pump is sucking up fluids: trap fluids upstream of pump.
the oil
8.2 Install a gas ballast system.
8.3 Pump temperature too low due either to insufficient operating time or because room is too
cold: install a preheating and rinsing system. Consult us for this.
8.4 Exhaust channelled and condensates returning into the pump: install a low point trap.

TRAINING

In order to ensure perfect aptitude in the use of the vacuum pump, the MIL'S company offers its own
training for the use of this equipment. It concerns users and technical personnel working on or near the
vacuum pump.
6.

CLEANING

Do not use corrosive products.
If the vacuum pump has to be cleaned, use a soap solution with a clean cloth.
Then wipe well with a dry cloth.
For disinfection, use swabs soaked in a disinfectant solution.
Frequency: as required.
