Multiquip 7434316 M16 Nut - OEM Replacement Part for Submersible Water Pumps

This M16 nut secures critical components in Multiquip ST-series submersible pumps, ensuring proper assembly and preventing loosening during high-vibration pumping operations. Designed for pumps rated up to 423 gallons per minute with maximum heads of 138 feet, this fastener withstands the demanding conditions of clear water pumping applications including standing water removal, excavation site drainage, and manhole dewatering.

The ST41230 and ST41460 submersible pumps feature chrome steel construction and industrial mechanical seals operating in oil-filled chambers. Proper fastening is essential to maintain seal integrity and prevent water intrusion into motor components. These pumps handle maximum solid sizes up to 0.6 inches (15.2 mm) and operate at temperatures up to 140°F (60°C), requiring hardware that maintains secure torque under thermal cycling and continuous vibration from 10 HP motors running at 28.6-14.3 amps depending on voltage configuration.

Compatible with the following Multiquip models:

• ST41230 (230V, 3-Phase)
• ST41460 (460V, 3-Phase)
