Revision as of 00:29, 6 December 2011
The Leo XKM60 is a periferal turbine pump and is probably the second most popular processor pump in the UK, second only to the TAM105.
It is sold as a clear water pump with a maximum temperature rating of 60°C, but it has been found by many home brewers to operate quite satisfactorily at temperatures up to 80°C and above, pumping oil and Biodiesel.
It is not self priming, but once primed has a very respectable suction lift for a pump of its size and can be used for transferring and filtering vegetable oil, provided the oil has a low viscosity.
The Leo XKM60 has the following specifications and performance:
- power(HP) … 0.5
- power(kw) ... 0.37
- Max. head ... 40m
- Max. flow ... 40L/min
- Max. SUCT ... 8m
- Inlet/Outlet connections … 1” BSP, female
- Body material ... Cast iron
- Impeller material ... Brass
- Leo XKM60 mechanical seal replacement
The body is removed by undoing three screws.
Check the body to lantern ring seal. This is a square section seal but if damaged could be replaced by a suitably sized "O" ring.
Removing the body reveals the impeller. Removing the body reveals the impeller. The impeller is a friction fit on the shaft and is fitted with a round ended parallel key.
The impeller material appears to be quite soft, so levering it off the shaft is not recommended. This simple puller was made to engage with the groove on the impeller boss.
Another view of the puller.
The puller engages with this groove. The impeller is not a very tight fit on the shaft.
This method wasn't tried but in the absence of facilities to make the puller, pincers could be attached and very gently tapped with a light hammer.
Once removed, friction marks can be seen on the inside of the impeller boss. The boss is slightly distorted by being centre punched at four points and it's simply the friction caused by the punch marks which holds the impeller laterally on the shaft.
