1 Overview
 
1.1 Application
The CCB type eat hutch slurry pump is developed based on the latest technologies and on experiences of water pump usage in China, and is reliable and easy to maintain. Its life time is much longer than that of screw pump and sump well pump. It is widely used to transfer eat hutch waste slurry, waste water, lipids, etc. Particles sizes up to ¼ of the pump bore size can be transferred due to its anti-clogging structure of large channel. Container type mechanical seal could also be installed for the auxiliary impellers to ensure no leakage while running.
 
1.2 Operation Parameters
 
Rotation rate: 980, 1480, 2950 (r/min)
Voltage: 380 V
Inlet and outlet bore size: 50 – 300 mm
Temperature: ≤ 150 ℃
Percentage of solid in the slurry: ≤ 25%
 
1.3 Nomenclature of Model Name
 
An example model name, 100CCB90-25, is used to explain its nomenclature:
100 --- Inlet and outlet bore size
CCB --- Eat hutch slurry pump
90 ----- Designed capacity at 90 m3/h
25 ----- Designed head of 25 m
F ------- An auxiliary impeller seal
 
1.4 Performance
 
Capacity: 3 ~720 m3/h
Head: 10 ~100 m
 
1.5 Work Conditions
 
(a) Temperature ≤ 150 ℃
(b) Percentage of solid in slurry < 25%
(c) Viscosity (7 ~23) x 106㎡/s
(d) Density < 1800 kg/m3
(e) Particle size (diameter) for different bore size (mm)

2 Structural Features
 
CCB eat hutch slurry pump has the following technical advantages:
(a) The impeller is of semi-open type, which increases pumping efficiency by 10 ~15% compared with those traditional screw pump or sump well pump, hence the motor power needed could be one grade down which will in return save energy consumption. Furthermore, the impeller is more cavitation-resistant.
(b) The sealing system consists of auxiliary impeller sealing and power-off sealing  based on a serial of fluid power, and is designed for frequent start/stop usage.
(c) The pump is linked directly to the motor. The impeller rotates clockwise when viewed from the motor end.
(d) There is a special desilting case at the bottom of the pump to collect precipitants which cannot be discharged from the outlet but could be removed through the door on the case.

7 Start Up And Shut Down
 
(a) Before starting up, check and confirm the rotation direction of the motor is correct and it rotates smoothly.
(b) Before starting up, make sure the vacuum gauge and pressure gauge are off. Switch them on when eat hutch slurry is transferred normally.
(c) Before starting up, open the exhaust valve or outlet valve to 1/3 position so that gas could be vented during self-suction, and then adjust them to their working positions when eat hutch slurry is transferred normally.
(d) Before shutting down the machine, make sure that the outlet valve is already switched off.
 
8 Operational Instruction
 
(a) The pump should be filled with eat hutch slurry before the first start. No filling is necessary for subsequent use.
(b) If there are crystals/precipitants in the slurry, the pump should be emptied through the draining door if not used for a long time. If used once for a few days, the pump should be switched on for 10 min every 24 hrs to reduce the accumulation of crystals/precipitants.
(c)  Please make sure that exhaust valve is open when there is bubbles or there is big static fluid column pressure during waste transferring, so that it could accelerate venting out gas and shorten the time of self-suction. When the pump is in automatic mode, an automatic exhaust valve should be installed between the pump and the outlet valve.
(d) The pump should be run strictly within its specifications (like capacity, head and the absorption).  The exceeding its capacity will cause cavitation and damages on the motor.
(e) Make sure the bearing is well lubricated. Replenish or replace it with No. 3 lithium base grease when 2-pole motor runs over 2000 hrs, 4-pole and 6-pole motors over 4000 hrs.
(f) For outdoor usage in winter time, the pump should be kept warm after shut down. Otherwise, empty the pump to prevent frost crack.
 
9 Trouble Shooting
 
Problems
Causes of problems
Solutions
No fluid out
1. The pump is not filled with enough slurry fluid
2. Filling port and/or vent valve is leaking
3. Inlet pipe is leaking
4. Rotation rate is lower than specification
5. Rotation direction is wrong
6. The absorption head is too high.
7. Sealing of the auxiliary impeller is damaged.
8. Fluid viscosity is too high
1. Filling up with slurry fluids
2. Tighten the valves
3. Check for leakage and amend it properly.
4. Adjust power voltage
5. Change it into the correct direction
6. Reduce the inlet pipe length or reduce the absorption head.
7. Change the oil sealing
8. Heat up the fluid or reduce the absorption head.
Insufficient flow rate
1. Small leakage in the inlet pipe line
2. Rotation rate is below specification
3. The desilting door is full with precipitants
4. The outlet valve is not fully opened
5. The inlet fluid level is low, and the air is sucked in.
6. Pump head is lower than the total head of pipe system, and the model is not properly chosen.
1. Check the pipe and amend it properly.
2. Adjust power voltage
3. Empty the precipitants from the door.
4. Open the outlet valve more.
5. Increase the fluid level.
6. Select a proper model.
Noise and Vibration
1. Shaky foundation
2. Worn shaft
3. Motor and pump are not concentric.
4. Damages in the springing block/ring in the coupling
5. The absorption head is too high, cavitation to the pump
6. Flow rate is too big, cavitation to the pump
7. Blockage to the impeller 
8. Air intake
1. Reinforce the foundation
2. Replace the shaft
3. Recalibrate the concentricity
4. Replace the springing block/ring
5. Reduce the absorption head
6. Reduce the flow rate using the outlet valve
7. Clean the impeller
8. Make sure the inlet fluid level is high enough before operation
Bearing heating
1. Motor and pump are not concentric
2. Damaged bearing
3. Dried or degraded lubricant
1. Recalibrate the concentricity
2. Replace the bearing
3. Change the bearing
The leakage of the pump
1. Damages in the mechanical sealing
2. Damage on the auxiliary impeller
2.1 leakage at the starting up stage, but no leakage while working
2.2 leakage at starting up and working
2.2.1 damaged sealing to the auxiliary impeller
2.2.2 the actual head exceeds the specification.
2.3 leakage after shut down
1. change the mechanical sealing and bearing
2.   
2.1 Initial filling is too much, but not a problem.
2.2  
2.2.1 replace sealing to the auxiliary impeller
2.2.2 use another model or adjust the actual working pressure
2.3  change the power-off sealing
