Slurry Pump Wearing Parts Replacements

SLURRY PUMP WEARING PARTS REPLACEMENTS

The wear rate of a solids handling slurry pump is a function of the severity of the pumping duty and the abrasive properties of the material handled. Therefore, the life of slurry pump wearing parts, such as impellers and liners, varies from slurry pump to slurry pump and from one installation to another.

Slurry Pump Wearing Parts must be replaced when the performance of a given pump no longer satisfies the requirements of a particular installation. Where a slurry pump is used on a particular duty for the first time, and especially where failure of a wearing part during service could have serious consequences, Tobee Pump. recommends that the slurry pump be opened at regular intervals, parts inspected, and their wear rate estimated so that the remaining life of the parts may be established. For installation of new slurry pump wearing parts, pls contact Tobee Pump.

STOCK LEVELS
Spare parts for Slurry pumps consist mainly of liners, impellers, bearings, shaft sleeves, seals, and shaft seal parts. Depending on the expected life of each part, you should keep a number of slurry pump spares of each in stock to ensure a minimum of downtime. Major plants typically stock an additional bearing assembly for every ten (or less) slurry pumps of the same size. This enables a quick exchange of the bearing assembly in any one of the slurry pumps. Often this operation is carried out when slurry pump wearing parts are being replaced. The removed bearing assembly can then be inspected in a workshop, overhauled if required, and kept ready for the next slurry pump. In this way, damage is prevented and all slurry pumps are always kept in optimum conditions with a minimum of downtime.

PART NUMBERS
Slurry pump parts are described by a part number consisting of three segments.

1. The (1) to (5) digit alpha or alpha/numeric prefix which references the relative slurry pump or frame size of the part.
2. The (3) digit numeric "basic part number" which indicates the part type.
3. The (3) digit alpha/numeric material code.

The following are example part numbers:

Prefix	Basic Number	Material Code
F6 For 8/6 FAH	147 Impeller F6147A03	A03 Ni-Hard
E4 For 6/4 EAH	110 Volute Liner E4110A05	A05 Hi-Chrome

You can use Slurry Pump components diagrams to determine part numbers for your slurry pump minus the material code. Tobee Pump. recommended spare parts lists should be used to verify the complete part number for your slurry pump, including material codes.

If you have any question concerning the proper part number or material code for your application, please contact your Tobee Pump representative or the factory.
