FAQ's

Yes. Fluid Metering pumps will self-prime to 15 feet vertical dry and 26 feet wet.

The hammering sound is usually an indication of CAVITATION. Cavitation occurs when the suction side tubing ID is too small to allow adequate flow of fluid to the pump. CAVITATION can cause problems such as hammering, flow variation, bubble formation, loss of prime and eventually pump damage.

Yes. Clean in place, autoclaving, or complete disassembly for brush cleaning are acceptable methods for cleaning without loss of system operating efficiency for Fluid Metering sanitary pump heads.

Dead volume is the amount of fluid remaining in the pump after discharge that is unusable in the application due to the risk of aspirating air. For low volume dispenses or low flow rates, Fluid Metering has special low dead volume pump heads, "LF", which utilize low flow fittings that facilitate bubble clearing in the pump.

Fluid Metering pumps are positive displacement and, in general, viscosity independent. However, viscous fluids should use lower RPM drives (400 RPM or less) with pump heads adjusted to longer piston strokes. There is no absolute value for the maximum viscosity of a Fluid Metering pump. For extremely viscous fluids, pressure feeding on the inlet side of the pump and/or heating of fluid aid in feeding fluid to the pump. Fluid Metering also manufactures temperature-controlled pump heads "WT" to help maintain fluid temperatures up to 360 F as it flows through the pump.

Fluid Metering can search through our reference material as well as our comprehensive application database to make recommendations. However, a quick and easy way to determine compatibility is to consider what materials of construction are currently used in your piping, fittings, vessels, and containers to handle your product. There are also reference compatibility charts available in print and online. The chemical manufacturer's MSDS data sheets may contain compatibility information as well.

Fluid splashing when dispensing is caused by the fluid being dispensed at a high velocity. The fluid velocity can be decreased by either reducing the drive RPM or by changing the dispense tip to one with a larger orifice. Dispensed tip design can have an influence on the velocity and pattern of dispensing to reduce splashing as well.

No. Fluid Metering’s Duplex Mixer Pump can meter two different fluids proportionally up to 500:1 ratio. The two pump heads are driven by a single variable speed drive motor and can maintain the fluid ratio while infinitely varying the overall flow rate.

Yes. Fluid Metering’s core CeramPump® technology can be easily driven by belt, chain, shaft coupling, or connected directly to special motor drives.
