1  Overview

1.1  Application

CCB Kitchen Waste Disposal Pump is developed based on the latest technologies and experiences of water pump usage in China, which 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 10－6㎡/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. So 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.
