The Advantages Of  Blackmer Sliding Vane And Gear Pumps

Sliding Vane Or Internal Gear?
Both Can Be Excellent Choices

Because they operate via the positive displacement (PD) pumping principle, Blackmer Sliding Vane and Gear Pumps possess many operational advantages when compared to non-PD technologies.

Especially when they are tasked with loading, offloading, transferring and circulating thin or thick, moderately abrasive liquids and liquefied gases.

The advantages of Blackmer sliding vane and gear pumps in critical product-handling applications include:

• Volumetrically consistent and reliable performance, even in severe-duty applications
• Ability to operate at high temperatures up to 650ºF/343ºC (internal gear) and 500ºF/260ºC (sliding vane)
• Flexibility to successfully handle different product types, viscosities, thicknesses, densities and vapor phases
• A wide performance range that enables fast pumping times even with continual system changes
• Self-priming ability that can create suction lift of up to 30 feet (9.1 m)
• Numerous sealing options: packed, single and double seal, and sealless magnetic coupling
• Ability to pump both forward and backward simply by reversing motor rotation
• Electric motor, hydraulic and truck PTO driver options

While these shared characteristics help make sliding vane and internal gear pumps an obvious choice, they do have some operational differences that make each technology best suited for different applications.
