HDRP Centrifugal Pump (OH2)

API Standard - 610

HDRP Series centrifugal pumps have special impellers and volutes and are suitable for continuous operations with small capacities at high manometric heads. Under these conditions, conventional centrifugal pumps could not operate without the installation of a system to control capacity or recirculate excess flow via bypass.

The models in this series comply with API 610 standard (latest edition) and can also be supplied in the In-Line OH3 (HDR/IL) or vertical “Sump Pump” VS4 (HDRP/VT) version.

Operational Parameters

Capacity: ___________________________ 0,25 ~ 25m3/h

Total manometric height: _____________ up to 300m

Maximum Rotation: ______________________ 3600 RPM

Temperature: __________________________ -100ºC ~ +400ºC

Pressure: _______________________________ up to 51 bar

Project Features

Full compliance with the latest edition of API 610 standard.
Complete range of materials according to API 610.
Heavy duty bearing housing.
Heavy duty shaft, low L3/D4 to minimize deflection, optimizing the life of mechanical seals.
Maximum interchangeability of components.
Improved convection cooling by adopting suitably located and sized fins.
Dry axis.
Open rotor specifically for low flow work and with compatible hydraulics.

Advantages

Pumping of small flows and high manometric height without the need for excess flow recirculation lines, or high-cost high-speed pumps.
Semi-open radial type impeller, designed to reduce axial loads to a minimum regardless of the suction pressure.
It does not have wear rings and its large axial clearance allows it to operate within its operating temperature range without the risk of seizure.
Back-pull-out pumps for ease of maintenance.
Large seal box to accommodate all types of mechanical seals.

Applications

In the pumping of refined petroleum products: diesel, gasoline, kerosene, naphtha, column reflux, column charge, heavy gas oil, reboilers, residual flash, stabilizer feed, stabilizer reflux, fuel mixtures, heat transfer, hot oil, column bottoms, injection, hydrocarbon transfer, boiler circulation, sour water, boiler feed, etc.
