Flow Chart

Shinmaywa Norus Pump Flow Rate Chart

Determine Waterfall Pump Size

Determine Head Pressure:

Step 1: Measure the distance (to the nearest foot) of the tubing from the pump to the waterfall and divide by 10.

Step 2: Measure the distance (to the nearest foot) of the waterfall from the top to the water's surface. (Head)

Step 3: Add the results from steps 1 and 2 to equal Total Head Pressure.

Example: Total tubing is 10' and the height of waterfall is 5' the required head pressure is equal to 6 feet.

{(10/10) +5} = 6' Head Pressure

Desired Water Flow:

The table below can be used as a good estimate of the required flow rate based on personal preference. Typical desired water flow is about 1,800 gallons per hour (gph) for every foot of width of waterfall discharge (weir).

For Example: Using a smooth waterfall discharge that is 2.5' wide with a desired waterfall thickness of 3/4" thick will require a flow rate of 4,500 gallons per hour.

(2.5' width x 1,800 gph/ft) = 4,500 gph.

Pump needed will produce 4,5000 gph @ 6 feet of head.

Water Fall Thickness*

*Table is based on a waterfall discharge of 1 foot wide.

"Quality Pump!"Jack of Sterling Heights, MI

I was very impressed when I received this pump. It appears to be very well made and it is in my pond and working well. The long 32'power cord was a plus.

"Junk"El Banner of Covington, KY

My installer told me to buy one of these to replace a previous pump. I purchased the Shinmaywa and it failed in less than a year. Then the company I bought it from wouldnt cover the warranty due to "all of the problems with the pump company". I paid for a new one and it failed in 2 months. JUNK ****Hi El, I'm sorry to hear of the experience you've had with these pumps, we've not had any issues with our supplier and very little if any problems with the pumps. I'm not sure how long ago you purchased the pump but if you have the pump and receipt we may be able to assist you with a warranty replacement.
