SolidC has a stainless steel shroud for protection of the motor, and the complete unit is supported on four adjustable legs.
 
Shaft seals
The SolidC pump is equipped with either an external single or a flushed shaft seal. Both have stationary seal rings in acid-resistant steel AISI 329 with sealing surface in silicon carbide and rotating seal rings in carbon. The secondary seal of the flushed seal is a long lasting lip seal.
