Atlanta Asphalt Shingle Plant Replaces & Upgrades Hot Paratherm Pumps

A distributor’s sales team engaged Vulcan Pumps on a hot oil pump application. We set up a joint call with VULCAN PUMPS meeting with plant engineers to determine performance requirements and physical restraints. After careful review of the customer process detailed solutions were provided to the customer.

•SIHI Pump was originally size for 250 gpm @280’ TDH, customer complaint cover two major concerns:

  1. Pump developed only 70 gpm, which would allow for the possible over heating of the Paratherm.
  2. Pump lip seal was leaking and customer attached piping to carry away this continued leakage.

•Plant engineer knowing of systems process changes overtime increase both the flow rate and pressure requirements for a potential pump replacement.
