Pump Solutions

Moving bitumen, heavy asphalt binders, and coal tar at road construction plants and hot-mix facilities presents an extreme thermal challenge. At ambient temperatures, bitumen turns into a solid, unpumpable block; at high operational temperatures, it transforms into a viscous, sticky fluid that quickly hardens inside cold pump clearances. We break down the engineering best practices for specifying steam and hot-oil jacketed gear pumps to eliminate cold-start lockups and secure continuous transfer across asphalt mixing terminals.
