PREMIER P501 series can handle excess liquid carryover without any difficulty, even if it arrives as massive slugs
20 vane rotors handle air more efficiently
Ease in maintenance as bearing bracket is externally mounted
Power efficient
No pressure throb
Enhanced capacity can be achieved when handling saturated gas by using inlet spray nozzles provided near the
      suction flanges of the pump.
All components are 100% interchangeable with *NASH 904 series
Standard material of construction is Cast Iron, also available in SS 304 and SS 316

Constructional Features

Body, Heads & Cones are made of close grained heavy duty Cast Iron, Rotor is made of Spheroidal Graphite (SG) Iron free from cavities and blow holes. The Shaft is made of Carbon Steel and carries the one and only moving part, the Rotor which is dynamically balanced for a vibration free running. The Shaft is carried on both the ends by bearings which maintain the close running clearance between working parts throughout the working life of the Pump.
Bearings are grease lubricated before shipment and require no further lubrication for approximately six months.
The pumps can also be supplied with contact parts in solid or cladded SS 304 and SS 316.
