Anti-gravity loops
An anti-gravity loop (AGL) must always
be fitted to systems where the pump is
positioned above the dome of the cylinder
(see fig 12). The AGL which limits aeration
of the hot supply to the pump is formed by
bending the pipework downwards for
250mm, as it exits the No Stop Essex flange,
before rising again to the pump.
(See figure 14).
Combi boilers and water heaters
As these appliances are invariably supplied
directly from the cold mains – they are not
suitable for this range of pumps, unless
pumping from a cold water storage cistern
via a universal pump.
Horizontal cylinders
As horizontal (Torpedo) cylinders are problematic for boosted systems consult PumpWise
on 0191 516 2002 for guidance and correct use of an approved top entry flange.
S flange
Complete with compression pump outlet and the open vent connections. Also supplied with
an adaptor to connect to 1” male and female top entry cylinders. (See fig 13).
