PDP Series Positive displacement dosing pump

The right dosing choice

PDP Series MAIN ELEMENTS TO SUPPORT OUR PRODUCTS

Versatility Different piston sizes are available to suit each application, starting from 1,3 until 4,000 l/h.

Reliability The high degree of accuracy and reproducibility with high quality materials selection make the piston pump series PDP to assure the maximum reliability.

Quality Appropriate materials are selected for each application.

Positive displacement plunger dosing pump Type A-I and AP-A I FEATURES PDP series positive displacement plunger dosing pump are manufactured according to API standard 675. Multiplex drive units with different performances can be coupled between them, independently from the size and stroke number. Stroke adjustment can be carried with the pump at rest or in operation. Accuracy is better than 1% from 10 to 100% of maximum output. Lower NPSH requires with normal operating conditions in function of the head type.

PUMPING HEADS Pumping heads are made in standard execution: S.S. 316 or PVC.

and on the smaller plunger are installed double check valves to improve precision.

STROKE ADJUSTMENT Stroke adjustment can be carried out: - Manual: by a linear micrometer crew. - Electrical: by servo motor with 4-20 mA signal or upon request interface PROFIBUS or other BUS - Pneumatic: by pneumatic servo control with signal from 3 to 15 PSI.

HIGH PRESSURE EXECUTION These pumps use the same crank mechanism of the pumps “AI ” type but the difference is on the hydraulic part that must be suitable to satisfy very hard requirements.

A wide range of other materials like HASTELLOY, ALLOY, PTFE, PVDF, PP are according to the liquid to be dosed. Piston gaskets are of the lip type design and are available in a wide range of materials ( FPM, EPDM, SILICONE, ADIPRENE). Liquid handled maximum temperature ➢- 90°C with S.S. 316 pumps heads. ➢- 40°C with PVC pump heads.

PLUNGERS Are made in S.S. 316 or Ceramics:

SUCTION AND DISCHARGE CONNECTIONS Normally are threaded but they can be supplied also flanged. All the pumps have a ball valve standard

The best performance for the applications is achieved by optimal section of plunger material and seal design.

PDP Series Correct installation and THE BENEFITS OF FLUID CONTROL ASSURE - Increase efficiency and pump life. - Decrease maintenance and operating costs. The control of fluid dynamics is essential to ensure efficient and safe use of process systems. Uncontrolled fluid in motion can physically destroy a pumping system including the pumping, valves, meters, back pressure valves, inline instrumentation and equipment.

2 SAFETY VALVES

4 PULSATION DAMPENERS

1 FILTERS We suggest to install filters (on the suction pipe) to keep back impurities that can be presented on liquid to dose or coming from pipeline system. The use of filters assures a trouble-free dosing.

2 SAFETY VALVES Safety valves are designed to protect the pump and chemical feed system from over pressure damage ‘caused by defective equipment or a blockage in the chemical feed line.

Positive displacement plunger dosing pump accessories 3 BACK PRESSURE VALVES Back pressure valves apply positive discharge pressure to a metering pump system to prevent siphoning and eliminate varying down-stream pressure.

4 PULSATION DAMPENER Metering pumps have a pulsating flow. Both positive displacement pumps and quick closing valves start and stop fluids that are in motion. Positive displacement pumps derive their pumping action by capturing a given amount of fluid in a chamber and pushing it out the pump’s

discharge. Each pump cycle includes a suction stroke during which fluid flow is stopped. This pumping action produces an acceleration/deceleration of the fluid, creating units of uncontrolled energy, resulting in PULSATION, observed as pressure spikes. Pulsation dampener is required for two reasons: ➢- To reduce high, non - permissible pressure fluctuations. ➢- To create a nearly continuous flow.
