Pear-Prinz®
Range Single- and twin-pair positive displacement pumps

Serie-HR — HD SERIES
HD Series Technical Sheet

PERA-PRINZ® screw pumps are externally supported rotating positive displacement pumps. One or two pairs of screws working without making contact ensure a constant, pulsation-free flow rate combined with a high suction capacity with very low NPSH values.

The supply is not limited to pumps only
3P Prinz also provides:

1. Skid or Custom Skid type mounting base

2. Instrumentation

3. On-skid piping with Valves

4. Control system

5. Auxiliary equipment

Executions and Special Materials
3P prinz can produce the full range of products with special materials for the wet parts of pumps.
Starting from cast iron to special alloys, such as:
Inconel® – Hastelloy® – Alloy 20 – Duplex/Super Duplex.
Material selection arises from the service fluid, temperature, and surroundings.
The design life of a pump is due to the proper selection of materials.

Features

Integral or reported screws
External bearing support with permanently greased rolling bearings
Transmission of motion, between pairs of screws, by oil-bath gears that ensure quiet and long-lasting operation
Mechanical seal (Simple or double) or premitreccia, with possibility of heating or cooling of the same
Pump body with cooling or heating chamber
Integral pump body or with reported liners
Pumps can be constructed in horizontal or vertical execution

3P Prinz® Double Screw Pumps for Heavy Loads

The double profile, specially designed by 3P Prinz’s engineering department, enables highly optimized rotor balancing, far better than the ISO 2.5 grade required by the API 676 standard.
Advantage of using this type of screw profile: drastic reduction in vibration, increased life of bearings and mechanical seals, and less heating of the whole system.
