Centrifugal Pump HDRP/D (BB2)

API Standard - 610

HDRP/D centrifugal pumps (BB2) are two-stage process pumps designed for heavy-duty use in high-pressure and high-temperature applications with extremely low capacities. They meet API 610 Standard (latest edition) and have two “low-flow” type impellers with “center-line” bearing mounting (BB2 standard).

Operational Parameters

Capacity: ___________________________ 1,5 m3/h ~ 24m3/h

Total manometric head: _____________ up to 630 m

Maximum Rotation: ______________________ 3600 RPM

Temperature: _ _____________________ up to 400ºC

Project Features

HDRP/D centrifugal pumps (BB2) are horizontal two-stage, radially split, between-bearings (BB2) centrifugal pumps that comply with API 610 (latest edition). The two open radial impellers are of the low-flow type and positioned to minimize axial and radial forces. The typical advantages of single-stage pumps (HDRP) such as high stability under low flow conditions and low NPSHr are maintained in the HDRP/D.
The seal chamber complies with API 682 standard. The seals are cartridge type, single or double (pressurized or not) and can be used according to the needs of each specific application. The pressure in the seal chamber is equalized through a balancing line, allowing the seals on each side to be of the same class.
The shaft design allows working at a critical speed above 120% of the design rotation and with shaft deflections in the sealing face region within the limits, as required by API 610.

Advantages

It does not have wear rings and has adequate axial clearance to work within the operating temperature range without the risk of seizure.
The housing is assembled in the center-line configuration (BB2) to minimize thermally induced misalignment.
Suction and discharge nozzles are ANSI compliant – 600 psi and configured with top/top orientation.
Rotors are dynamically balanced, keyed, and positively locked to the shaft.
Baseplates comply with API 610.

Applications

Applications range from water and light hydrocarbons at low temperatures to corrosive fluids and other services at high or low temperatures in environments such as refineries, petrochemical plants, gas processing, and offshore installations.
