General Pump Disassembly Methodology
Please review the general repair (section 5.7) and cleaning and inspection guidelines (sec-
tion 5.7.7) before beginning these procedures.
The Hale Flex Series single stage booster pumps design separates the four pumps into two
groups based on the volute. The first group (the AP, CBP, and MBP) utilizes a one-piece volute
(see Figure 18) while the second (the RSD) utilizes a three-piece volute (see Figure 19). This
makes the RSD pump disassembly unique among the Hale booster pumps. The RSD three-piece
volute consists of the suction head, the body (volute), and the pump head. Additionally, the pump
is unique in that the volute provides a side discharge flange to support ancillary equipment (typi-
cally a TRV).
