IMPORTANT SAFETY INFORMATION | |
WARNING
Please read the following safety instructions before operating
Vacuum Pump

􀀂 Do not operate the pump without the coupling guard properly attached. Operating the pump without the coupling guard exposes personnel in the vicinity of the pump to risk from rotating drive components.
􀀂 Do not operate the pump with oxygen-enriched gas (greater than 21% by volume) in the suction line, unless the pump has been prepared with an inert fluid suitable for the application and equipped with seal and start/stop purge system. Pumping oxygen-enriched gases with mineral oil or other non-inert fluids and without proper purges can cause fire or explosion in the pump, resulting in damage or serious injury.
􀀂 Take precautions to avoid prolonged or excessive exposure to oil mist or process materials emanating from the discharge of the pump.
􀀂 Do not allow the pump to discharge into an open atmosphere. Applications where process vapour contains environmentally unfriendly chemical vapours, pump discharge must be connected to the properly sized scrubber system to neutralize the harmful c

FAQs

What are the key safety warnings before operating the vacuum pump?

The manual warns against operating without the coupling guard properly attached and against pumping oxygen-enriched gas without inert preparation and proper seal/start-stop purge systems. It also emphasizes safe discharge handling, avoiding restricted discharge valves, and disconnecting electrical power before disassembly or service.

How should the pump be intended for use according to the manual?

The manual states the ESPH series pumps are built to meet exacting standards and should be installed, operated, and maintained per the instructions. It requests following system compatibility and operating recommendations, noting that using the pump for unapproved applications may invalidate warranties.

What maintenance topics are covered in the manual?

Maintenance includes establishing a maintenance plan, checking oil level, following an inspection schedule, inspecting pipelines and connections, replacing the inlet filter, performing coupling drive alignment, performing solvent cleaning, and flushing the cooling jacket. It also includes dismantling and assembly procedures and troubleshooting guidance.
