Multiquip 335400101 Base Pump MQD-3H - OEM Replacement Part

The base pump assembly provides the foundational mounting and structural support for MQD-series diaphragm pumps, serving as the critical interface between the pump mechanism and the power unit. This component houses the pump's internal working parts and ensures proper alignment and stability during operation. When the base pump shows signs of cracking, warping, or stripped mounting points, replacement is necessary to maintain pump integrity and prevent catastrophic failure during dewatering operations.

This base pump assembly is engineered specifically for Multiquip MQD-series diaphragm pumps, designed to withstand the demanding conditions of construction site dewatering, flood control, and high-volume water transfer applications. The precision-machined design ensures proper fitment and reliable performance under continuous-duty cycling.

Compatible with the following Multiquip models:

• MQD2H
