standpipe and is designed to transfer fluids
compatible with a fluid-wetted path of
carbon steel, aluminium, Fluoroelastomer,
and nylon 11
When equipped with a 2 in PT (e) bung
adapter (purchased separately) pump can:
• Mount to wall (with use of wall bracket)
and can be used with an optional siphon
wand kit See Table 2, page 7, for details
• Utilize extensions (not included with

An optional low-level cut-off valve can be
used with an extension This valve prevents
pumping of air should fluid level become low
and is recommended when using a fluid
