Anjon Monsoon Pumps MS-550
Anjon Monsoon Submersible Pumps MS-550
The Anjon Monsoon submersible pump is designed for use in fountains, waterfalls, and smaller ponds. An energy-efficient electromagnet is sealed in epoxy-filled housing. The drive shaft and electromagnetic rotor are recessed in the motor housing: near silent operation and extremely low operating cost. It features a hybrid drive system that combines the high flow characteristics of a direct drive pump with the energy-saving efficiency of a mag drive pump. The asynchronous drive motor can be controlled with a variable speed controller (not included) that permits you to increase or decrease pump flow as needed. The impeller passes solids up to 0.25” and the pump is engineered for 24-hour continuous use. It also features an overload sensor that prevents burnout. This submersible pump contains no oil, making it safe for fish, wildlife, and aquatic plants.
Note: The speed controller does NOT work with the MS8000, MS10000, MS12500, MS3000100, MS5200100, MS6100100, MS80001000, MS10000100, MS8000200, MS12500200 & MS15000200 models.

CHOOSING THE RIGHT SIZE TUBING FOR MY WATER FEATURE
When Sizing your Freeze Flex Pond Hose, make sure you choose a pipe that will not restrict the flow of your pump! If your hose is 1.5" and you buy a 6,000 GPH pump, your pipe will only allow 4,400 GPH to pass through it. You will be wasting money on electricity and paying for a stronger pump that will not give you the desired result. You will need to run an additional pipe or change your hose to get the desired flow rate! Many people expect to achieve greater flow by simply buying a larger pump. They do not realize that flow will not increase unless the tubing can also support this increased inflow. Please do not let this happen to you. Using the chart above, you will be able to easily determine the best size tubing for your pump size. Do not use pumps on an extension cord. They must be run on a dedicated 15 Amp GFI circuit.

HOW MUCH WATER IS HELD BY MY WATER FEATURE?
Length x Width x Average Depth x 7.48 = Gallons
Example: A rectangular pond that is 15’ long, 10’ wide and 1.5’ deep is... 15’ x 10’ x 1.5’ x 7.48 = 1683 Gallons
Oval Ponds
Length x Width x Average Depth x 0.8 x 7.48 = Gallons
Example: An oval pond that is 15' long, 10' wide, and 1.5' deep is... 15' x 10' x 1.5' x .08 x 7.48 = 1346 Gallons
Round Ponds
Radius x Radius x Average Depth x 3.14 x 7.48 =Gallons
Example: A round pond that has a 12' diameter and is 1.5' deep is... 6' x 6' x 3.14 x 1.5' x 7.48 = 1268 Gallons
Streams
Length x Width x 0.25 x 7.48 =Gallons
Example: A stream that is 20' long, 3' wide, and 3" deep is... 20' x 3' x 0.25 x 7.48 = 112 Gallons
