WC Macerators
WC Grinder Pump
A WC grinder pump is a compact unit mounted behind or beside a toilet that grinds toilet and lavatory waste with stainless steel blades and discharges it through a small-bore pipe (typically 22–32 mm) to the drainage system. It enables toilet and bathroom installation where the drainage line is distant or positioned below without requiring additional excavation or large-diameter pipework.
Models are available that accept connections from toilet, lavatory, shower and bidet. Selection and supply are made by quote according to application.
