1. Usage and Application Range

Tobee® TSB series centrifugal sand pump mainly supplies to solids control circulating system of
oilfield drill rig, and be used to provide drilling liquid with a certain discharge capacity and
pressure to sand, desilter and mud mixer, to assure these equipments work efficiently.
The TSB10×8×14 centrifugal sand pump applies to over 3000-meter-long drilling rigs, with big
viscosity and specific gravity drilling fluid. The TSB8×6×14 centrifugal sand pmp applies to
over 3000-meter-long drilling rigs. The TSB8×6×11 centrifugal sand pump applies to under
3000-meter-long drilling rigs, also can be can be used to supply mud to triplex mud pump as a
filling pump. The TSB6×5×11 centrifugal sand pump applies to truck-mounted drilling rigs or
pocket drilling rigs. The TSB4×3 centrifugal sand pump is usually used as measuring pump or
replenishment pump.The TSB3×2 centrifugal sand pump is usually used as clean water pump.

2. Main Structure, Feature and Working Principle

Its main parts are pump shell, impellers, bearing block, pump axle, bearing, shaft coupling,
wearing plate, seal apparatus, oil seal, motor and base. the following is the structural dwg. of the
pumps.

The Series Centrifugal Sand Pump has these features:
(1) Open impeller,apply to transport high viscosity drilling liquid.
(2) Combination seal for a long service life.
(3) Use universal bearing houses and bearings,convenient to maintain and cut the costs.
(4) The major parts are made from antiwear nodular iron,and long service life.
The prinple is that under the motor, the impellers of the pump rotate at high speed, the dring fluid
is sucked into the suction pipe. After the drilling fluid flows through the suction pipe and gets
enough energy and velocity under the centrifugal force, the drilling fluid is expelled continuously
out of the pump.

4. Seal Apparatus Maintenance

TSB centrifugal sand pumps adopt combination seal(shown in Fig-1),consist with mechanical
seal, packing,packing bushing,seal box,holdingdown bolt,antiwear sleeve etc.

Seal apparatus sketch

1-Mechanical seal 2-Packing ring 3-Seal box 4-Packing bushing

5-Holdingdown bolt

Copyright © TOBEE PUMP 6-Antiwear sleeve

www.tobeepump.com

Maintenance:
a. When use a new sand pump or the mechanical seal is changed newly, keep the packing
bushing in relexed state to avoid wearing out the antiwear sleeve prematurely.
b. After working one year,and the mechanical seal fails,the pump is sealed by packings by
compressing the packing bushing with the holdingdown bolt.When the packing bushing fails to
adjust,add a packing(packing section is 12mm×12mm).
c. After shaft sleeve antiwear layer wears out, change the mechanical seal and shaft sleeve in
time.

5. Bearing cavity maintenance

a. Grease is 3# extra press lithium base grease,input it 50ml bearing every 3 months
b. Cleaning bad grease of bearing cavity every half year.

6. Installation and Adjustment

A. Installation
a. The pump should be placed on well site as possible to the sand, the desilter or the
compounder.
b. The pump suction port should be over 200mm to the tank bottom,and the discharge port of the
working machine connected to the pump should be over 2m to the suction port.As the following:

Wrong Right

≥2m

≥200

Copyright © TOBEE PUMP www.tobeepump.com

c. Motor cable must contain earth wire preventive electric leakage.
d. Assure a good sealing of all the connection,no fluid leakage and air leakage.
e. After installing , make sure the pump rotation direction is correct.!!!

B. Adjustment

If there is no special requirement,our pumps are used the following coupling.

1-Motor coupling 2-Pump coupling 3-Coupling rubber

Good service life of the pump and driver depends upon good alignment through the flexible
coupling.If the electric motor was mounted at the factory,the pump and motor were in alignment
when shipped.The alignment between the driver and pump should be inspected after installation
to ensure that transportation or other handling has not caused misalignment of the unit.Poor
alignment may cause failure of the coupling, pump, or motor bearings, or of either shaft.

The recommended procedure for coupling adjustment is by the use of a dial indicator, as
illustrated in the following.The dial indicator is attached to one coupling half with the indicator
button resting on the O.D. of the other coupling half to measure offset misalignment.To measure
angular misalignment,the indicator is positioned so that the button rests on the face, near the
O.D.,of the other coupling half. Rotate the shaft and dial indicator one full revolution while the
other shaft remains stationary and note the T.I.R.Unless otherwise specified by the coupling
manufacturer,offset misalignment should be limited to 0.4mm(0.005) inches and angular
misalignment should be limited to 0.4mm(0.005)inches.Adjust misalignment by loosening driver
or pump mounting bolts and re-tightening or shimming as required.

Copyright © TOBEE PUMP www.tobeepump.com

Measuring Offset Alignment Measuring Angular Alignment

In areas where a dial indicator arrangement is not available, an adequate job of alignment

can be done with a straight edge.This method is especially useful if the coupling used contains an

all rubber drive element.

To check offset misalignment, lay the straight edge in line with the shafts on the O.D.’s of

the coupling halves.There should be no gaps under the straight edge. Check two locations 90º

apart.Angular misalignment can be checked by measuring the gap between coupling half

faces.There should be no more than 1/64″ gap under the straight edge or 1/64″ variation in the

gap between coupling halves.

7. Operation

Prior to start the motor, make sure the motor rotating direction is kept same with the
marked direction on motor housing. Otherwise, reset the motor terminal to make sure the
direction is consistent.!!!
a) If the sand pump is newly installed or re-used after a long period of time, check the lubrication

and junction carefully. First of all, lubricant is filled into the seal cavity and the bearing
cavity.Never is there foreign matters in the pump cavity.
b) The impellers of the pump are connected to the pump axle through screw. At the first usage,
ensure that the rotating direction is correspondent to that labeled on the pump shell, or the
impellers will be removed to touch the protection plate in front of it and the pump will be
damadged quickly.
c) The sand pump should be started at the condition that the suction vavle is open and the
exhaust vavle is closed. After running for 1~2min, open the exhaust vavle and adjust the pump
pressure. If the pump pressure and flow rate too high or too low, or the motor is too hot, adjust
the opening of the exhaust vavle till the pump is running stably.
d) When the fluid surface in the circulation tank is low, turn off the pump and restart it after the
tank is filled. Vapor crrossion can be avoided.
e) In cold season or for a long time of no running, remove the screw plug under the bottom of the
pump shell to let the fluid out for preventing it from condensing.
f) Often check the temperature of the pump axle and bearing. Not higher than 40℃(the total
temperature is ambient temperature +40℃).
j) If abnormal sounds occur in operation, stop running at once. Restart the pump after troubles
are disposed.
h) The new sand pump and its seal apparatus have been carefully tested and checked after
production. Do not wrench or take out the adjustment screw.

10″=6,9″=5 etc. 14″ use lettet A;
2. Second X equals frational data in1/8′s. Therefore 1/8″=1, 1/4″=2 ,etc…Thus a

10.5″impeller is coded as 64, 12″impeller is coded as 80, 13.25″impeller is coded as 92
etc…
3. YYY－the metric diameter of impeller，therefore 12″ is coede as 305mm，11″ is coded
