Product Description

Vertical, mixed flow

Vertical shaft, mixed flow, single- or multistage pumps with closed impellers, consisting of a discharge head, column assembly and bowl assembly. On request, they can be manufactured with open or semi-open impellers. The impellers are balanced in accordance with ISO 1940 Class 6.3.

Vertical Line Shaft Mixed Flow Pumps are used for transferring clean or dirty lake, river and dam water that may contain solid particles and fibres, as well as industrial raw water.

Design features

Submerged bowl assembly

Mixed flow, vertical column design; for lake, river and dam waters and industrial raw waters.

01Bowl assembly submerged

As the bowl assembly is submerged, there is no suction problem at start-up.

02High efficiency

Operating costs are low thanks to their high efficiency.

03Flanged column pipes

Provides ease of assembly and disassembly.

04Single-stage or multistage

Mixed flow, single-stage or multistage design.

05Closed or semi-open impeller

Mixed flow closed or semi-open impeller types are used.

06Vertical mounting

Generally installed vertically; the discharge head may be above or below floor level.

Configuration options

Configuration to suit the installation

Discharge head position, drive type, lubrication and sealing are determined together according to the operating conditions.

Discharge head

Above groundBelow groundIn-line suction – dischargeT-type discharge head

The T-type discharge head is used at low capacities and heads.

Drive

VHS electric motorV1 electric motorDiesel drive with 90° gearboxCoupling or cardan shaft connection

The motor can be positioned on the discharge head or on the upper floor.

Lubrication

With pumped waterWith greaseClean water (special)Oil (special)

Column intermediate bearings are lubricated by the pumped water or by grease; as a special design, they are made with clean water or oil lubrication.

Shaft sealing

Soft packingSingle mechanical sealDouble mechanical sealCartridge-type mechanical seal

Selected according to the type of pumped liquid and the operating conditions.

Intermediate bearings

BronzeRubber

The intermediate bearings in the column assembly can optionally be made of bronze or rubber.

Impeller type
