Installation

- Install on suction or discharge side of system. We suggest installing between the pump discharge and the reservoir tank if you are using a tank.

- Install on the discharge side to allow use of a purge valve for easy one step cleaning.

- Manifold two or more filters for applications with flow rates higher than 100 GPM.

There are several factors to consider when specifying the VuFlow filter for any application. Mesh selection; flow rate; operating pressure; operating temperature; and chemical contact are some of the most important considerations.

Mesh selection
Proper mesh selection is the primary consideration which insures the highest performance of the VuFlow filter. Mesh selection is directly relative to filter maintenance requirements. One should choose the coarsest mesh possible for a given application to avoid high filter element maintenance requirements. Mesh should be sized such that the smallest passage or opening in the system is just slightly larger than your mesh opening. This mesh selection method allows non-problematic particulate to pass through the system. See our mesh conversion chart in the VuFlow literature for mesh opening sizes.

Proper mesh selection is also important when considering the type of particulate to be filtered. Well and municipal water sources usually contain dramatically different particulate than above ground water sources. Well and municipal water supplies typically contain heavier than water particulate such as sand. Sand centrifugally separates well in mesh sizes of 24 to 140. Once sand is centrifugally separated it is easily flushed out of the filter through the purge valve. Some periodic manual cleaning of the filter element may be necessary with fine meshes 250 to 1000.

Above ground water sources often contain air borne or biological particulate that do not readily flush out through the purge valve. Therefore; a course mesh selection is particularly important when filtering air borne or lighter than water particulate because the filter element will have to be cleaned manually. One should take special consideration to allow easy access to the filter element for cleaning when filtering above ground water sources. A side stream; a bypass; or a duplex filter installation are good installations that allow easy access to the filter element for screen cleaning without interrupting water flow.

Flow rate
Flow rate considerations are a balance between pumping efficiencies and centrifugal separating capabilities. Heavier than water particulate like sand centrifugally separates well with the VuFlow filter. Separating ability is at its best when the flow rate is high. Unfortunately a higher flow rate leads to a higher pressure loss. High pressure losses relate to low pumping efficiencies. Each installation is unique and may be able to accommodate various pressure losses. A good pressure loss for high spin centrifugal separation in the VuFlow filter is between 5 to 10 psi for heavier than water particulate. However; lighter than water air borne or biological particulates do not centrifugally separate. The lower the pressure loss the better with lighter than water particulates. Low pressure losses relate to high pumping efficiencies. Also lighter than water particulate usually require a larger screen surface area. Select the size of the filter relative to the total gallons per minute verses psi loss; keeping in mind the type of particulate to be filtered. The size of the pipe used in your system may not be the best indicator of the filter size selection. See pressure loss graph in VuFlow product literature.

Operating Pressure and Temperature
The operating pressure limit for the VuFlow filters is 150 psi at 73ºF (23ºC). The PVC filter body of the VuFlow filter is similar to other PVC plumbing fittings and pipe. Factors such as pressure surges; high cycles; and high temperature adversely effect operating pressures of all PVC products. reduce the adverse effects of pressure surges and high on-off cycles by following industry accepted design recommendations keeping flow velocities below 5 feet per second. PVC fittings and pipe weaken as the temperature increases. VuFlow recommends that the operating pressures of the PVC filter not exceed 100 degrees Fahrenheit. Many PVC fitting and pipe manufactures recommend a pressure rating decrease as temperature increases. The VuFlow filter pressure rating also decreases similar to PVC fittings.

Chemical contact
The VuFlow filter is recommended for use with water only. Many chemicals used in various applications can possibly damage the filter to the point of failure. The clear cover is the most chemically sensitive component of the VuFlow filter. VuFlow manufactures a high performance clear cover that is more chemically resistant. VuFlow has chemical compatibility information available. However; VuFlow recommends that all chemicals used in the filter be thoroughly tested for compatibility by the end user prior to use.

Frequently Asked Questions:

Q: HOW DO I SELECT THE PROPER FILTER SIZE?
A: SELECT FILTER SIZE BASED ON FLOW RATE.
1" - 1-25 GPM
1-1/2" - 10-50 GPM
2" - 18-100GPM
THE SIZE OF THE PIPE USED IN YOUR SYSTEM MAY NOT BE THE BEST INDICATOR. NOTE: SPIN OUT SEPARATION IS BEST AT HIGHEST FLOW RATES. PRESSURE LOSS IS BEST AT LOWER FLOW RATES.


Q: WHAT IS THE BEST UNIT FOR WELL WATER TO MY IRRIGATION SYSTEM AND INTO MY HOME?
A: THE BEST CHOICE IS A 1 1/2" FILTER WITH 100 MESH. (CHECK THAT YOUR GPM DOES NOT EXCEED 50 GPM) PART # NT 1-SO 100 P

Q: WHAT IF THERE ARE CHEMICALS IN THE WATER?
A: OUR FILTERS ARE RECOMMENDED FOR USE WITH WATER ONLY. WE HAVE CHEMICAL COMPATIBILITY INFORMATION AVAILABLE. WE ALSO OFFER A HIGH PERFORMANCE CLEAR COVER THAT IS CHEMICALLY RESISTANT.

Q: WHAT IS THE MAXIMUM OPERATING PRESSURE?
A: DO NOT EXCEED 150 PSI AT 73 DEGREES F° ON ALL FILTERS.

Q: WHAT IS THE MAXIMUM OPERATING TEMPERATURE?
A: DO NOT EXCEED 100 DEGREES F AT 40 PSI ON ALL FILTERS

Q: WHY DOES THE SCREEN IN MY FILTER PLUG SO FAST?
A: THE MESH IS TOO FINE. CHANGE TO A COARSER MESH.

Q: WHY DOES THE SCREEN STAY PLUGGED AFTER PURGING?
A: TRY CHANGING TO A COARSER MESH OR THE SEDIMENT IS LIGHTER THAN WATER AND WILL NOT PURGE.

Q: ALGAE GROWS INSIDE THE CLEAR COVER. WHAT CAN I DO?
A: USE A COVER GUARD OR ALUMINUM FOIL AROUND THE COVER

Q: WHY DOES THE FILTER LEAK BETWEEN BODY AND COVER?
A: TIME TO REPLACE O-RINGS

Q: WHAT CAN I USE TO CLEAN THE ELEMENT?
A: HOLD UNDER RUNNING WATER. FINE SEDIMENT WEDGED IN THE SCREEN MAY BE REMOVED WITH A SOFT BRUSH. SOAK IN ½ BLEACH AND ½ WATER FOR STAINS.
