2.6 Maintenance Safety
• Always isolate the power supply before working on the pump
• Always follow the safety procedures for handling the product being pumped
• If the hose has ruptured, the lubricant may be contaminated with product – care must be
taken to handle the mixture appropriately
• Do not stand near the pump while the hose is being removed – if the hose is expelled too
quickly, it could cause serious injury
• Never try to install a hose without the front cover in place
• Never remove the front cover when the hose is still in position
• When removing the front cover of the VF50 - 80, lifting equipment should be used to support
the weight. Always use lifting equipment safely in accordance with the manufacturer’s
recommendations. The pump is provided with a lifting eye, which can be fitted into the
threaded hole of the front cover, (located by removing the top left of centre front cover
fastening bolt) to assist with lifting. Take care not to drop the front cover as this is likely to
cause serious injury
• Do not stand in the immediate vicinity of the pump when operating with the inspection cover
removed; follow safety procedures for operation of pump with inspection cover off
• Care should be taken to support the weight of the rotor shoe whilst the bolt is being removed
– similarly care should be taken not to drop the shoe after removal from the pump rotor
• Extreme care must be taken when removing the rotor. When the rotor comes away from the
pump shaft, it will tend to swing out on the lifting equipment, potentially causing serious injury
- stand well clear
2.6.1 Long Coupled Assemblies
• Do not strike the pump shaft, the inner race or the bearings
• Once installed, the bearings are greased for life; do not lubricate after installation
