We developed the Sur-Line system to prevent mud and other fluids from passing into the power section from the fluid end section of the mud pump, and to prevent fluid from going from the power section into the fluid end section.

The Sur-Line system uses a unique floating seal system that bolts into the wall between the power section and the fluid end section. The seals inside this housing seal against the OD of the pony rod, thus preventing fluid from passing between the two sections of the mud pump.

We carry parts to fit pumps from most major manufacturers. Sur-LineĀ® systems are simple enough to be installed by the rig crew, or can be installed by our technical service department at the rig site.
