Description, Care and Maintenance
Internal Tank Jets
The Internal Tank Jets (Fig.11a) are supplies with the M2 unit, and are installed (by the customer) inside the
reservoir tank, to keep the slurry product in the tank moving. This function assures the elimination of dead
spots in the tank and a consistent mixture of fluid.
The internal tank jets are connected together in series, usually by a manifold design, (suggested by STS)
were all jets receive the same amount of fluid and pressure. This manifold design is supplied with fluid from
one of the outlets on the filter / shear housing (Fig.11b). The outlet has a ball valve to control the flow,
(Fig.11b) and should always be in the open position, unless you are cleaning the filter / shear (described
earlier) or performing repairs on the system. If the valve is not closed, when preforming these tasks, a
siphoning action can occur, pulling fluid from the tank and into the external piping. The internal tank jets
requires little or no maintenance and will only require attention if they become clogged. Flushing the entire
system daily with clear water should eliminate any problems with this piece of the system. The fluid passing
through the internal tank jets is at a very high pressure and extreme caution should be used when viewing
the inside of the tank.
The internal tank jets also acts as a relief valve to the system and relieves the pressure spikes caused when
the flow to the drill rig or second reservoir tank is interrupted.
