Split-Flow pumps allow synchronized movement of jacks using only one pump

Split-Flow checkball pumps are ideal for heavy lifting applications using strand jacks, which can eliminate the need for hiring expensive cranes. In this application, strand jacks were used to position a bridge pier.

Multiple outlet pumps can provide up-to 10 flows for synchronized movement of the jacks. These pumps are used for lifting and skidding operations throughout the world.

This is a prime example where a customer selected a Dynex checkball pump because of our Proven Performance. Trusted Service.
