Pond Pump Know How:

Major Differences Between Centrifugal Pump Types:

LOW HEAD

Generates useful pressures to 10 ft of water pressure (4-5 psi).

A low head pump may not be very effective in backwashing certain sand type filters (Predators and some others) which require higher pressures and flows for backwash cycle.

Use a medium head pump when pumping to a waterfall more than 10 feet above the ponds' surface. You can also use a low head pump when pumping through low head filters (Aquadyne, mat filters, large open type filters, etc.).

Most efficient type

MEDIUM HEAD

Generates useful pressures to 30-35 ft of water pressure (12-15 psi).

If pump is medium head, while effective in backwash cycle, it may not be energy efficient during majority of use.

Use a medium head pump when you must pump to higher elevations, pump the water through sand filters or other filters which require high pressure.

Least efficient, most power

TWO SPEED

Operates as both low head and medium head pumps. When higher flow and pressure is required, as for filter backwash, the pump is switched into a higher speed.

When such pressure is not required, the pump is switched back to the lower speed to benefit from it's greater energy efficiency. Superfalls 2 speed pumps deliver maximum efficiency during low speed operation, and maximum power at high speed.

The 1 hp 10-8KMH2S operates with the same flow/pressure characteristics as the single speed 1 hp medium head version when at high speed, and theenergy efficient10-4000LH when at low speed.

The Best of Both Worlds!

CORRECTLY INSTALLING THE PUMP!

You may install your centrifugal pump in a dry box or pit lower than the water level in the pond to assure it stays primed. If you install the pump in a box, you should provide for fresh air ventilation by blowing fresh air into and out of the box.

You may also install your pump above ground (limit pump height to 1' or 2' above pond water level). Be sure to install a swing check valve on the suction of the pump, and another one on the discharge side of the pump.

These will maintain prime on the pump, and also prevent back-flow of water from your filter, waterfalls, etc. when necessary to open your leaf trap.

We recommend that you consider installing a strainer basket or leaf trap before the pump to protect it from leaves and trash. You may want to mount your pump on a mounting base or plate which has in turn been secured in concrete. To reduce energy costs and improve the flow in your stream or waterfall, you should minimize the height and the length of your waterfall and stream.

Your bio-filter could be located with its outlet supplying a waterfall and/or stream.

If you are building a large pond, we recommend that you consider use of two or more pumps rather than attempting to get full flow with a single pump. Multiple pumps offer some real benefits besides just energy savings. For example, two 10-7000LH pumps can provide up to 230 gpm flow for much less energy than one large pump and also allow you a measure of insurance against loss of flow. Multiple pumps also allow you to shut off one or more pumps for more energy efficient winter or night time operation. Note: bio-filters require 24 hr flow for proper operation.

Our large medium head Superfalls pumps can supply flows to 250 gpm. You should determine the flow you need and use two or more pumps to achieve the required flow at the head pressure needed. Your initial cost to purchase multiple smaller pumps will be slightly more, but this extra cost will be returned to you many times over in electrical savings and peace of mind.
