PRODUCT
DESCRIPTION
These operation and maintenance instructions apply to the DESMI ESLH pump in /-17
execution.
The ESLH pump is designed for horizontal assembly with the pressure flange pointing
upwards. The pump is a single-stage end suction centrifugal pump equipped with stainless
steel shaft, balanced mechanical shaft seal mounted in a separate chamber with cooling ribs
and fan cooling and closed impeller. Between impeller and shaft sealing, a carbon bearing is
built in that is flushed from the pressure side of the pump.
The pump can be used as standard for water with temperatures up to 180°C
– possibly higher
temperatures in agreement with DESMI. Higher temperatures may be permitted if, for example,
any working pressure allowed in the pump housing at the current temperature, pumped liquid,
maximum suction pressure, pump size, speed, current shaft seal and maximum ambient
temperature make it possible. Max. operating pressure and speed ranges are specified in
operational data.
If the pump is to be used for liquids other than water, other rubber types are likely to be used
for O-rings and any other materials for the other liquid-affected parts of the pump - contact
DESMI accordingly.
