Design Features
The Asphalt Pump series are economical General Purpose pumps utilizing
a "floating" rotor design. The jacketed head and rotor
bearing sleeve are designed to allow passage of satuated steam or heat
transfer fluid to melt asphalt that has solidified in the pump prior to
startup.
Sealing options include:
- packing
- cartridge lip seal
- cartridge single mechanical seal
- cartridge single O-ring seal
- cartridge double mechanical seal
- cartridge double O-ring seal
Pumps with jacketed heads cannot be furnished with an integral pressure
relief valve, but optional non-jacketed heads may be provided with a
jacketed relief valve on the "KK" through "N" size
pumps.
