6.2.5 Typical disassembly - Metal-Lined
The XHD slurry pump is available in two models: the basic version, referred to as XHD and the XHD Val-
ue Option. The method of disassembly and assembly can vary between these models. The XHD is a
front pull out design. Typical disassembly steps can be followed for both the XHD and XHD Value Option.
The suction half casing and attached components can be removed for further disassembly and replace-
ment of the suction side liner (562) and adjustable seal ring (822, XHD only) as necessary. After remov-
ing the impeller (101) by disengaging the knock-off ring (149), the gland half casing (100D) can remain
