All-metal progressing cavity pump handles hot fluids
Here’s the Vulcain progressing cavity pump, a new product with an all-metal design that is capable of pumping hot (as high as 660° F.) and viscous fluids. It’s suited for use in thermal recovery of heavy oil.
The company says that the rotary action of its pump outperforms beam pumps in overall system efficiency and is less fragile than electric submersible pumps. The pump provides low submergence production capability and can operate at low downhole pressures and higher viscosities.
The pump’s seals reduce the risk of on-site leakage, and the compact installation footprint reduces its visual impact on the landscape, the firm notes.

New shaft seal pumps lubricant back to bearing
New low-friction Waveseal shaft-sealing solutions feature a specially molded lip to form a sinusoidal or wave pattern around the shaft surface.
Seals enable lubricant to be pumped back to bearings and protect against contaminants in applications including gearboxes, motors, transmissions, drive systems, speed reducers, and pumps.
This pattern enables lubricant to be pumped back to the bearing for optimized lubricant retention while pushing dirt away from the lip-shaft surface (regardless of which way the shaft is turning) to protect against contamination.
The specially designed lip additionally generates 25-35% less heat at the contact point (minimizing premature seal failure due to heat checking, blistering, hardening, or lubricant breakdown); generates 20% less friction torque or drag; curbs shaft wear; and provides greater lip lubrication compared with standard lip versions, the firm says.
