P300 Series High Pressure Metering Pump
Metering pump flow rates from 2 to 80 GPH
The P300 Series metering pumps are designed specifically for high pressure applications >1000 PSI and ≤ 2500 PSI. For pressures ≤1000 PSI please refer to our P200 Series metering pumps. As with all the other P Series metering pumps, the P300 is designed to handle a broad range of fluids, everything from clear water to viscous or abrasive slurries. The P300 Series is capable of operating within the 50 to 2500 PSI range.
The pumping performance satisfies API 675 standards related to steady-state accuracy, linearity and reputability. The P300 Hydra Cell pump as illustrated above is comprised of a D04 Hydra Cell pump attached to a gearbox. The gearbox provides a mechanical means of reducing pump shaft speed and maintaining proper shaft torque, thereby reducing the motor horsepower required along with the size of a variable frequency drive (VFD) if used to operate the pump within a 10:1 turndown ratio.
Most VFD's have some programmability and can be interfaced with a customer supplied PLC. We also offer our own touch-screen PLC/VFD control package called the Control Freak which comes preprogrammed based upon factory testing of your specific pump; it also has a calibration feature to adapt to your specific fluid and installation conditions.
We can provide a complete pump/motor/VFD/PLC assembly, however we'll require additional information from you to properly size and select the motor and optional controllers. The best thing to do is to view our P300 Hydra Cell pump catalog pages and then use our metering pump inquiry form to provide us with the design criteria.
Reliability + Simplicity = Low Cost of Ownership
The only wetted components are the elastomers and the check valve assemblies. While the elastomers do not have a wear life, the check valves do wear and require periodic replacement. Expect 9-12 months of continuous operation (6570-8760 hours) before needing to replace the check valves. Abrasive fluids, perhaps involving spray drying ceramic slurries would be expected to wear-out the check valves quicker, although we offer them in erosion resistant materials such as ceramic and tungsten carbide. Abrasive and corrosive applications require special thought regarding pump sizing and pump RPM (fluid velocity through he pump head).
The check valves are replaced by removing the pump manifold, that's the first plate and it is attached to the pump with (8) cap screws. There are no special tools or training required, with replacement typically completed within an hour and often without removing the pump from the process area. If the elastomers become damaged due to fluid incompatibility or over-pressurization, they can be easily replaced by removing (2) additional cap screws holding the check valve manifold to the pump body.
We can supply single and three phase motors, inverter-duty motors, explosion-proof motors, etc... so ultimately you'll need to contact us via phone or email to provide us with all of the design criteria. The best way we can begin assisting you is to use our online application based inquiry form, which we usually reply to the same day or within 24 hours.
