Minent Fluid Controls Pro. Minent® “A controlled volume pump (also called a “metering”, “proportioning” or “chemical injection pump”) is a reciprocating power pump used to accurately displace a predetermined volume of liquid in a specified time period and is driven by power from an outside source applied to the pump mechanism. It includes a mechanism for varying the effective plunger, piston or diaphragm displacement. ”

Suction Lift Atmospheric pressure always pushes down on any fluid surface. When the pump diaphragm creates a negative pressure in the pump head, atmospheric pressure forces fluid up the suction tube to fill the cavity. If the pump pulled a perfect vacuum, the maximum suction lift possible on earth, pumping water, is 34 feet. 9 Pro. Minent Fluid Controls Pro.

Specific Gravity Sulfuric acid density = 15. 34 lbs/gal Therefore: Water density = 8. 34 lbs/gal S. G. = 1. 84 Ammonia density = 5. 25 lbs/gal Therefore Water density = 8. 34 lbs/gal S. G. = 0. 63 Because atmospheric pressure forces fluid into the pump head during the suction stroke, if the fluid has a specific gravity greater than 1. 0, the suction lift ability will be reduced. Specific gravity is independent of viscosity, and does not impact pump capacity, only suction lift capability. 11 Pro. Minent® Specific Gravity is the fluid’s density in relation to the density of water (S. G. 1. 0). For example:

Viscosity is a measure of a fluid’s resistance to flow. Viscosities greater than that of water increase friction loss and result in reduced pump capacity. When selecting a pump for viscous fluids: Oversize the pump Put springs in the valves to help seat the balls Reduce stroking rate to minimum possible Keep stroke length as great as possible Provide flooded suction with oversized suction line 13 Pro.

Vapor Pressure Matter exist as solids, liquids or gasses. The state of matter depends on the compound itself, the pressure around it, and the temperature. The Vapor Pressure of any fluid relates to the pressure and temperature at which it flashes from a liquid phase to a gas phase. It is defined as the pressure exerted when a liquid is in equilibrium with its own vapor. 15 Pro. Minent® The higher the vapor pressure, the more likely the fluid will vaporize on the suction side of a pump during the suction stroke, causing cavitation.

Backpressure Valve When discharging into a vacuum line, use two backpressure valves to ensure maximum protection against siphoning. The backpressure created by the two valves (and the injection valve) is not additive. Whichever valve is set at the highest pressure will determine the system pressure at the pump. 22 Pro. Minent® Regulatory agencies may require use of two anti-siphon valves in certain applications such as adding fluoride to drinking water.

In a reciprocating pump system, the entire fluid column between the pump and injection point stops flowing at each suction stroke and is forced to flow at each discharge stroke. Overcoming inertia creates large momentary pressure spikes on the pump system. 23 Pro. Minent® Pulsation Dampener
