THE POND GOVERNOR

• (1) - Large 40mm (1½ inch) diameter outlet

• (2), (3) & (4) - Large 40mm (1½ inch) diameter inlets

• (5) & (5a) - Large 20mm (3/4 inch) flow control apertures

• (6) - Diffuser

• (7) - Flow control passageway

• (8) - Special ratchet rubber seals and swivel joints

• (9) - Hollow filter member

• (10) - Cleaning brush

• (11) - Solid waste separator

• (12) - Housing sump

• (13) - Cleaning hand wheel

• (14) - Rubber housing vent bung

Filter housing size - 310mm x 300mm x 185mm (12 ¼ inches x 11 7/8 inch x 7 3/8 inch).

Filter housing size including inlet valves - 450mm x 300mm x185mm (18 inch x 11 7/8 inch x 7 3/8 inches).  

For ease of use and understanding the numbers 1, 2, 3 and 4 are moulded into the housing, adjacent the appropriate inlet or outlet. Outlet (1) is easily identified by the blue adjustable apertures (5a). Inlets (2), (3) & (4) are multi functional and can be used for mid water inlet, bottom water inlet and vacuum attachment functions as required. 

• It can be used with or without flexible hoses.

• It can be used to pre filter the pond's water from just below the surface, mid water and the bottom, simultaneously or separately.

• Has no internal moving parts to harm small fry.

• Has large clog resistant apertures.

• All filter inlets, surface, mid water, bottom inlet and vacuum, have adjustable apertures.

The Pond Governor, shown in Figure 2, is a combined separator and pre filter that is fitted to the pond pump inlet. The Pond Governor's outlet (1) is connected to the pond pump inlet by a flexible hose. The filter housing has four inlet positions, (2), (3), (4) & (5).

Inlets (2), (3) & (4) use 25mm (1 inch) flexible hoses (not supplied) of any appropriate length, and inlet (5) uses adjustable apertures. The water and solid waste drawn through housing inlets (2), (3) & (4) enters the diffuser (6) then slows down as it enters passageway (7). The water and solid waste drawn through housing Inlets (5) also slows down as it enters passageway (7). As the flow decelerates into chamber (11), the heavier solid waste settles into the housing sump (12) and the filter member (9) mechanically filters the lighter suspended solid waste.  

The lighter suspended solid waste collects by design on the surface of the filter member (9) to form a natural micro filter. The low suction through the large surface area of the hollow filter prevents the micro filter clogging the sleeve. This combined with the natural biological build up formed during use on both the inside and the outside of the hollow filter sleeve can sift down to 100 microns (0.004 inch) giving unprecedented capabilities. The pre-filtered water inside the hollow filter member (9) is drawn through housing outlet (1) to the pond pump inlet.  

The dual purpose filter member sleeve that functions as a natural micro filter and a strainer for pond vacuuming is constructed using durable polypropylene at 560 microns (0.022 inch).

Figure 2: A-G 

• Flow arrow A shows solid waste and water as it enters the filter housing inlet.

• Flow arrow B shows pre-filtered water as it exits the filter housing outlet.

• Solid waste is indicated by the black shaded areas.

• The solid waste and water is separated using hydraulics as it enters the filter housing. • The solid waste is directed out of the water flow and settles in the housing sump.

• This pre-filtered water is then mechanically filtered by the filter member sleeve and passes through the outlet 1 as indicated by arrow B.

Performance Option

Inlet 2 is used with inlet 3 and 4 plugged to increase the sump capacity to contain solid waste when used as in Section 4.3 in the User Guide.
