Installation Notes – Suction Flange
(See Figure 6a-3: “Typical Suction
Flange Option.”)
To install the flange follow the preced-
ing steps in the reverse order paying
attention to the following:
❑ Review heading 6a.1 “General Preparation” on page 85.
❑ Install a NEW gasket. Apply Loctite to all screws and tighten in a criss-cross
pattern to ensure an EVEN seal.
❑ Refer to Table 6-1: “Typical Torque Values Chart” on page 79 for recom-
mended fastener size, material and torque value.
❑ Set up apparatus for pumping and test pump. Check for leaks at the piping
and seal areas before returning apparatus to operation.
Volute (Pump Body)
On certain pumps, the volute is sealed to the pump housing using an O-ring
and gasket. The O-ring must be inspected for splits, cracks, flat spots, etc. All
other pumps are sealed by a gasket only. (See Figure 6a-4: “Typical Pump Dis-
assembly Overview” on page 92.)
