Product Description

NDh Series Single Stage Radially Split Barrel-Insert Pumps
NDMh Series Radially Split Multistage Segmental / Barrel-Insert Pumps



Applications: Designed for handling refined products at the process plants in the oil-refining industry.

Design: ANDh and ANDMh series pump units consist of a centrifugal pump and an induction motor in the explosion-proof version, which are mounted either on a common base plate (if the nominal power of the motor is less than 400 kW) or on separate base plates. The pump and motor shafts are connected by means of a flexible coupling. The pump units shall be rigidly anchored to the foundation, and piping shall be also rigidly connected to the pumps.

The pumps as components of the pump units are electrically driven horizontal, between-bearings, centreline-supported, single- or multistage segmental or barrel type centrifugal pumps with hydraulic balancing of rotor axial thrust.

Flanged nozzles are oriented: radially to the top (discharge) and tangentially horizontally sideways (suction). Counter flanges have a weld neck.

Upon the Customer’s request, the suction nozzle may be arranged vertically.

In order to enable the pump to withstand hot and cold shocks and thus to allow for free expansion of static components during the pump operation whilst maintaining coupling alignment, the pump feet on the drive side are rigidly dowelled to the base plate pedestal and the other end is pinned so that it should be axially moveable.

The pump rotor is carried either by the oil-bath lubricated antifriction bearings with forced cooling (if the nominal power of the motor is less than 400 kW), or by the oil-bath lubricated plain bearings (in case of the nominal motor power within 400 to 630 kW), or by the pressure lubricated plain bearings with lube oil supplied by a pressure lubrication installation (if the nominal power of the motor is over 630 kW).

Shaft sealing is by mechanical seals in tandem arrangement, which utilizes a pressurized barrier fluid, neutral to handled medium. Handled medium near the shaft seals is cooled by cooling liquid supplied into the thermal barrier chambers.

Sense of rotation of pump shaft is shown with a rotation arrow attached to the pump casing or to the bearing housing on the drive side.

The motor pump units shall be controlled by a process monitoring, control, warning/alarm and emergency trip system as required in PB 09-540-03.
