Description, Care and Maintenance
Filter / Shear System
continued
On top of the filter / shear housing (Fig.7) are two outlets that have 2” NPT ball valves connected to
them. One of the outlets (labeled) is connected to the internal jet gun inside of the reservoir tank (explained
further on in this manual) and the other outlet (labeled) is to be used as a discharge for the fluid after it is
mixed. The discharge can be connected to another reservoir tank or directly to the drill rig. To control the
flow of discharge, the ball valve can be used to regulate the flow. The speed of the pump can also be used to
control the flow and pressure of the discharge. It is up to the customer to decide the piping arrangement and
how they would use the discharge options. The discharge flow can have high pressure and high volume flows
associated with it, and should be treated as such. If you are unsure of the installation and routing of this
flow, contact Surface to Surface Inc. for more details.
Also on top of the housing is the outlet for the wash wand. The wash wand is explained in more detail
further on in this manual.
NOTE: Some units have a third outlet (shown in Fig. 7), which has a pipe plug in it. It can also be used as a
fluid discharge if needed.
CAUTION
TRAPPED FLUID MAY BE PRESENT
and will spill out when piping, hoses,
pump or filter shear are removed.
CAUTION
WHEN TRANSFERRING FLUID
to the drill rig, fluid pressure may
reach or exceed 50 p.s.i.
CHECK the drill rig manufacturers
specifications regarding maximum inlet
pressures allowed for their pump.
