Multiquip 14660000900002 Cover Suction NPT 4" QP-4TH - OEM Replacement Part

The suction cover is a critical sealing component that protects the pump casing at the suction port interface on 4-inch Multiquip trash pumps. This NPT-threaded cover maintains the sealed pump cavity necessary for proper self-priming operation and prevents air leaks that would compromise the pump's 25-foot maximum suction lift capacity at sea level.

Designed for high-volume trash pump applications, this cover works in conjunction with the clean-out system to provide access for debris removal while maintaining the pump's ability to handle solids up to 1.57 inches in diameter. The QP4TB series pumps deliver up to 555 gallons per minute through 4-inch suction and discharge ports, making proper sealing at the suction port essential for maintaining rated performance. Operating these pumps without proper suction cover sealing will prevent priming and significantly reduce pumping efficiency.

This cover is compatible with the following Multiquip models:

• QP4TB
• QP4TK
• QP4TZT10P
