KEY FEATURES:
ADVANTAGES OVER SUBMERSIBLE PUMPS:
• Dry mounting • Higher temperature capability
• No sludge build-up on the motor
• Duty flexibility by changing pulley sizes
• Belt drive protection • Blockages more easily removed
• Ease of maintenance Applications • Construction • Utilities
• Slurries • Industrial waste • Dirty water • Drainage • Dewatering
