LS600 PUMP — PUMPING INFORMATION

CLEARING SHUTTLETUBE BLOCKAGE

The shuttle tube is plugged if volume at the discharge end of the hose stops and the hydraulic oil pressure gauge reads 4400 PSI or more.

To clear a plug in the shuttle tube, great care must be taken as a dangerous condition will exist from pressure build-up inside the shuttle tube. (With the shuttle valve, the concrete can be pumped in reverse.) Use the following procedures to clear the shuttle tubes.

WARNING - SHUTTLE TUBES

DO NOT open any of the delivery system joint clamps.

“REVERSE” PUMPING PROCEDURE

A.Switch the pump into REVERSE. With pump speed at a medium-slow (approx. 12 strokes per min.) try to pull the “pack” back into the hopper with 5 or 6 reverse strokes.

B.Remix the concrete in the hopper.

C.Switch the pump into FORWARD. If it is still plugged, repeat “Reversing” procedure three times.

If concrete still does not move, proceed to the Shuttle Tube Inspection Procedure.

D.Carefully knock the end of the hose away from the reducer.

E.Chip the concrete out of the reducer with the pry bar.

F.Remove the reducer. From the discharge end, chip the concrete out of the shuttle tube with the pry- bar. If concrete cannot be loosened from the outlet of the shuttle tube, remove the clean-out plug on the bottom of the hopper to discharge the concrete.

G.Chip the blockage out with the pry-bar.

H.Flush the shuttle tube with water.

I.Before resuming operation of the pump, perform the “Reverse” Pumping Procedure to relieve pressure on the shuttle tubes.

WARNING - ACCUMULATOR PRESSURE

Make sure the accumulator pressure gauge reads ZERO psi. prior to performing any maintenance or inspection.You must follow lock out-tag out procedures.

SHUTTLE TUBE INSPECTION PROCEDURE

A. Stop the pump. Switch off the engine.

BThe senior or most experienced operator must warn all others to stand at least 20 feet away from the machine and turn their heads to face away from the pump.

C.The operator will position himself beside the reducing elbow at the pump outlet. Wearing safety glasses, slip the end of a pry bar (24" length of reinforcing steel rod) under the latch of the hose clamp and flip it up.
