Molten Metal Pumps Require Careful Engineering

Gusher has the experience to handle extreme temperatures

In molten metal pumping applications, the stakes are high. The pump must be constructed to move liquified potassium, sodium, zinc, lead and other metals safely and reliably at temperatures that can exceed 1200°F. With over 100 years in the pump industry, Gusher Pumps has decades of experience in the engineering and construction of molten metal pumps.

In applications where pure metal or alloys such as babbit and spelter are pumped, there are a number of design considerations. Pumps not engineered to withstand the intense heat of these applications can break down, causing process interruption and risking the potential for severe damage or personnel injury in the event of a leak or rupture.

Gusher’s Molten Metal Series vertical pump models have been engineered with cooling technology that protects critical pump components from heat damage. Molten Metal pump models are supplied with Class F motors or can be upgraded to Class H for added insulation and protection in higher temperature environments. Depending on the operating temperature, models are available with fan-cooled bearing housings (200-700°F) or fan-cooled and water jacketed bearing housings (700-800°F). At temperatures of 800°F and above, models are constructed with both a bearing housing water jacket and water-cooled shaft.

Molten metal pumps are available in electric or air driven models. Standard construction includes ductile iron and 316 stainless steel; other alloys are available based on application requirements. Gusher’s in-house sales and applications engineering team have decades of combined knowledge to customize pumps to solve difficult pump challenges.
