D.
MGEM shall have a minimum of 5 years of experience manufacturing medical air and vacuum systems.
E.
Written pre-approval is required for all equipment from other manufacturers.
ALL VACUUM TUBING SHALL INCLUDE:
A.
Type ‘L’, ‘M’, or ASTM B-280 ACR copper.
B.
Brazed with BCuP-5 Brazing alloy or equivalent alloy with at least 1000
˚F
melting point.
MEDICAL VACUUM PUMPS
Specifier: Determine the size of vacuum plant required and place on the medical gas schedule
1.
Provide a complete medical vacuum source, complying with all relevant requirements of the latest edition
of NFPA 99 and supplying medical vacuum continuously for the life of the equipment. The unit
shall be manufactured by Amico or pre-approved equal.
2.
All components shall be at least duplexed and valved (or check valved as provided in NFPA 99) to
allow servicing to any components devoid of interruption of vacuum supply to the facility during
any maintenance operation or any condition of single fault failure. Each pump exhaust shall be isolated by a
union fitting permitting capping for service removal.
3.
Furnish a complete plant consisting of pumps, receiver, and controls capable of providing the scheduled
capacity with one pump out of service. All capacities will be indicated in SCFM at 20 inches HG.
4.
System is modular or field separable, allowing for ease of shipment and handling on site. System is
completely factory assembled, requiring only interconnection between modules on site. Systems requiring
on site assembly other than interconnection are not acceptable (Remounting of components removed for
shipping is permitted).
5.
Each pump will be direct or close coupled to a NEMA rated High Efficiency TEFC motor with a service factor of 1.15.
6.
Each pump will include inlet and outlet flex connectors supplied by the MGEM.
A. Pumps
Vacuum pumps shall be provided as follows:
Specifier: select the paragraph below reflecting the preferred technology:
Oil-Less Contactless Claw:
1.
Provide non -contacting claw style rotary pumps. Internal construction is friction free and rotors are
non-contacting. Air end is oil free and requires no sealants. Each pump is air cooled and continuous
duty rated. Pump is provided with a single lubricated gearbox requiring oil change at minimum
20,000 hour intervals. Pump is provided with exhaust silencer. Pumps are provided by Amico
or pre-approved equal.
Lubricated Rotary Vane:
1.
Provide oil lubricated rotary vane pumps, dynamically balanced heavy-duty multi vane design.
Minimum vane life is 30,000 operation hours. Oil recirculation differential pressure with full
recirculation and multistage exhaust oil separation rated at no less than 99.998% efficiency. Each
pump is provided with an oil non-return valve, filter change indicator for exhaust oil separa tion
filters. Service to the oil filters does not require disconnection of the exhaust piping. The oil lubrication
system shall all be enclosed in one module to minimize oil leaks. Systems with external piping
for oil lubrication are not acceptable. Systems requiring separate additional external electric motors
for oil cooling are not acceptable. Rubber hose flex connectors and hose clamps are not acceptable
for assembling package. Pumps are provided by Amico or pre-approved equal.
