Where to get: pump for recirculating liquid - need high flow

[Robert Macy]

OT, but you guys know where to find everything!

Anybody know where to get a 'recirculating' pump system that sucks up
liquid [mainly water based] and jumps the pressure up into the
40-60psi or even more range and can supply several gallons per minute
[first pass estimate] against back pressure, like attempting to block
the exit nozzle. Hand held ON/OFF nozzle with a bore on the range of
3/16 to 1/4 inch, or 5/16 [1/8 inch is too small and suspect 3/8 is
too large] Like an air brush nozzle.

Need to be portable, 110vac, and run quietly.

Everything self contained: plastic/rubber tubes, pickup apparatus to
place in bottom of liquid container, hand held trigger nozzle with
push button ON/OFF control, and pump,

Any idea where to get this?

[Wild_Bill]

If you need pressure, not just flow.. a peristaltic pump will work well.
This pump uses rollers to continuously compress a loop of tubing to act as
piston-like motion for positive pressure flow.

Eventually the tubing loop needs to be replaced.. how often depends upon the
type of tubing used.

In choosing a pump suitable for your application, you'll need a fairly
acurate "guess" of the flow rate. The flow rate is related to the nozzle
size, which can usually be adjusted/replaced.

You could check with Grainger. Look for a soda machine pump. These

are bronze gear pumps and can be bought with a motor attached.

As to a complete package, not sure. For just the pump, here's what I'd
use:

SureFlo (sp?), they make wobble pumps that are self-priming, positive
displacement, high pressure, have an adjustable pressure cut-off
switch built in, and can handle small particles in the fluid (ie: it
doesn't have to be perfectly clean fluid). They also do a pretty
bang-up job of pumping oil out of big diesel engines (gensets) for oil
changes.

The smaller ones run on 110vac, take about 104 watts, can pump about 7
gallons per minute at 60 psi max, and cost about $90 US. No need for a
push button ON/OFF control, just stop flow, the pump will shut off on
high pressure, then start again when flow is started again and
pressure drops a bit.

The pumps themselves last forever. The motors, however, are the brush
type, so you'll need to know how to take them apart and replace the
brushes (it's pretty easy). If the pumps run about 8 hours per day,
the brushes will last about 6 months. You can re-brush them 3 to 4
times before the commutator gets too worn to run well.

They make yer typical small motor hum, and you can hear the wobble cam
as it rotates and compresses the three pumping chambers, but it's not
that loud.

You can order them to handle whatever chemical solutions you like.

I'll check about their ability to operate against head pressure.

Numbers for pressure and flow rate would be nice. The landlubbers
version of the bilge pump is called a "Submersible Sump Pump" which is
usually used to drain flooded basements. I have one of these:
<http://www.acehardware.com/product/index.jsp?productId=1272836>
Works great pumping water, but not so great pumping thin sludge and
gravel.

Regardless of type, you'll need to compromise between: flow rate,
pressure, back pressure (head), and power drain. Sump and bilge pumps
are made to move volumes of water, at fairly low power drain.
Therefore, you're not going to get much pressure out of them. Worse,
if you try to lift the water too high, the flow rate will decrease
until the pump can no longer lift the head of water. If you want
plenty of pressure, but little flow rate, look into a garden pond or
fountain pump, which will launch water to quite an altitude.

Your vague specifications also included something about "liquid,
mainly water based". All the aformented are for pumping water, not
sand, rocks, gravel, sludge, sewage, etc. If you cannot filter out
the debris at the intake, you're going to need a specialized pump that
can eat rocks and not destroy itself. For that, you'll need a sludge
or slurry pump, which uses a flap valve pump mechanism instead of
gears or a vane pump. For example:

These also have the advantage of being able to run without any water.

As for noise, good luck. If you shove too much water through the pump
to quickly, the pressure behind the impeller will drop sufficiently
low for the water to literally boil. That's called cavitation and
it's a major source of noise, inefficiency, and self destruction. If
you don't want noise, you'll need to carefully match your pump to your
application. (Unlike my former neighbors mis-sized hot tub pump that
made more noise than a diesel truck up to the day that the pump
literally exploded). In general, fountain pumps are made to be rather
quiet if that's an issue.

OT, but you guys know where to find everything!

Anybody know where to get a 'recirculating' pump system that sucks up
liquid [mainly water based] and jumps the pressure up into the
40-60psi or even more range and can supply several gallons per minute
[first pass estimate] against back pressure, like attempting to block
the exit nozzle.  Hand held ON/OFF nozzle with a bore on the range of
3/16 to 1/4 inch, or 5/16  [1/8 inch is too small and suspect 3/8 is
too large]  Like an air brush nozzle.

Need to be portable, 110vac, and run quietly.

Everything self contained: plastic/rubber tubes, pickup apparatus to
place in bottom of liquid container, hand held trigger nozzle with
push button ON/OFF control, and pump,

Any idea where to get this?

Thank you for the URL.

The pumps look like perfect form factor, pricing is good, but they all
use 12Vdc

I'll check about their ability to operate against head pressure.

Is the flow rate critical? You can generate 40-60 psi head with a
properly-sized centrifugal pump. But the flow might vary significantly as
the back pressure builds up.

For a flatter flow characteristic, a positive displacement pump plus a
pressure relief valve will give you a more constant flow right up to where
the valve opens. But this is more of a specialty setup and a pump expert
may need to be consulted.

Also, what's in the 'mainly water' that you'll be pumping? Pump resistance
to chemicals and/or abrasives might be an issue.
