Product Description
The Tuthill GlobalGear® internal gear pumps have tougher, more reliable parts that are easy to service and maintain. The modular design reduces switching costs saving time and money.
The GlobalGear® pump was developed based on customer input, and customer input in the process industries clearly points to the need for better gear pump reliability and specifically better seal reliability. The opportunity for better reliability is created by the situation that many pumps applied on viscous liquids are fundamentally designed for packing and later adapted to mechanical seals. In many cases, the seals being selected were designed for use with water-like liquids. Pumps designed for packing combined with mechanical seals designed for thin liquids are no match to offer extended reliability with demanding viscous liquid applications.
