Multiquip EM14843 Seat Dura Upper - OEM Replacement Part for Concrete Pumps

The upper dura seat is a critical wear component in the valve assembly of trailer-mounted concrete pumps, forming the pressure seal that controls concrete flow through the manifold during pumping operations. This precision-machined seat works in conjunction with the valve system to direct high-pressure concrete from the hopper through the discharge cone and into your delivery lines.

Designed for demanding jobsite conditions, this dura seat maintains the tight tolerances required for effective pumping of various concrete mixes including air-entrained, accelerated, and super plasticized formulations. Regular inspection and replacement of worn valve seats prevents material separation in the manifold, maintains proper discharge pressure, and eliminates jamming issues that can occur during extended pours or when pumping abrasive aggregate mixes.

This seat is engineered to withstand the continuous reciprocating action and abrasive wear from sand, rock, and aggregate passing through the pump system. Replace when you notice decreased pumping efficiency, pressure loss, or material leakage around the valve assembly.

Compatible with the following Multiquip concrete pump models:

• C30HDGA
• C30HDN
• C30HDNI
