HEAVY DUTY COAL MINE DEWATERING PUMP

BASE – a single piece base with integrated adjustment mechanism for impeller clearance within pump – bearing assembly locks into base using six or eight heavy-duty bolts
BEARING ASSEMBLY – all bearings assembled with highest quality tapered roller bearings in controlled environments to prevent lubricant and housing contamination – oversized shaft diameters and reduced overhang in the wet end contribute to long life and reliability in the field
CASING – split-case design allows for ease of access and maintenance on wet end parts – cast ductile iron with exterior ribbing provides increased pressure ratings and reliable service over time
WETTED PARTS
IMPELLERS – hard metal impeller – pump out vanes on rear and front reduce recirculation within pump, and aid in preventing seal contamination – optional castings of straight or semi-Francis vanes offer wider hydraulic options in single sizes
LINERS – heavy-duty hard metal liner – active engineered attachment mechanism to casing via threaded bolts as opposed to unreliable glue
THROATBUSH – adjustable via cotters to account for wear over time and increase efficiency
CHEMICAL COMPATIBILITY – operating PH range from 5 to 12
SHAFT SEALS – LIBRA offers a wide variety of seal options to suit any process requirements
