The Koshin 043060901 is an Original Equipment Manufacturer (OEM) replacement impeller engineered specifically for Koshin PBX7-50 series submersible contractor pumps running on a 50Hz electrical supply.

Key Specifications

• Brand: Koshin

• Part Number: 043060901 (Also referenced as 0430609)

Design & Features

• Rugged Construction: Unlike conventional metal cast impellers, PBX series impellers are crafted from highly wear-resistant polyurethane. This specialized material increases the component's lifespan by up to 300% when pumping abrasive fluids like sandy or muddy water.

• Restored Efficiency: Replacing a worn or damaged impeller restores the pump's original factory head pressure and maximum delivery volume, while ensuring the pump's internal forced-air cooling system functions correctly during low-water operation.

• Exact Fit: As a genuine Koshin factory part, it maintains strict mechanical tolerances to prevent impeller clogging and ensure smooth startup torque.
