Haight 7EU-VMS Positive Displacement Internal Gear Pump
The Haight 7EU-VMS internal gear pump is engineered for dependable fluid transfer performance in demanding industrial environments. Built with rugged ductile iron construction and equipped with a Viton mechanical seal, this positive displacement pump delivers reliable operation for oils, lubricants, petroleum products, chemicals, and other industrial fluids requiring consistent flow and pressure handling.
Designed around Haight’s proven “gear within a gear” internal gear technology, the 7EU-VMS offers smooth flow characteristics, self-priming capability, and efficient operation at standard motor speeds. Its compact design supports easy installation for close-coupled or direct motor mounting applications while minimizing maintenance requirements and operational downtime.
The absence of an integrated relief valve makes this configuration ideal for systems already equipped with external pressure protection or customized flow control solutions. The Viton mechanical seal enhances compatibility with higher temperature fluids and demanding industrial applications requiring increased chemical resistance.
