For most applications, there are generic produced pumps available on the market. However, there are always exceptions. For example, large volume water pumps, uncommon capacity or head ratio, specific NPSH availability, low RPM requirements, space constraints, environmental requirements, replacement of a pump where the OEM doesn’t exist anymore, unique equipment combinations (e.g. pump-turbine) or some other special requirement. Often this applies to water management (e.g. cooling water, condensate, drainage, flood control, fire-fighting).
Building on decades of pump manufacturing capabilities, we look forward to understanding your unique requirements and engineering a fit-for-purpose pump (combination). Apart from designing, manufacturing, testing, installing and commissioning the pump, we can also project manage a fully integrated package including drivers, gears, instruments and controls. Your total cost of ownership is on the forefront of our minds.
Axial flow pumps
When moving a large volume of water, with relatively low head, axial flow pumps are the way to go. Stork offers several engineered solutions:
SHG: horizontal, cat back, dry pit, single stage, axial flow
SH: horizontal, dry pit, single stage, axial flow, foot mounted
OPH: horizontal, submersed, single stage, radial split, diffuser type (axial)
OVOP: vertical, wet pit, single stage, axial flow, open top discharge
Vertical suspended pumps
Commonly used vertical pumps for a large range of applications with medium to large capacities and medium to high head. Our vertical wet pit pumps is the way to go: VO: single stage, radial flow, enclosed impeller, radial split, diffuser type (radial), multistage possible
VOA: single/multiple stage, mixed flow, enclosed impeller, radial split, diffuser type (bowl)
VSO: single stage, mixed flow, open impeller, radial split, diffuser type (bowl)
VOP: single stage, axial flow, radial split, diffuser type (axial)
Concrete volute pumps
When reliability is key and maintenance needs to be kept to a minimum, concrete volute pumps are your #1 choice. The pump volute is made out of concrete and is an integral part of the civil structure. Excellent durability, life span and total cost of ownership combined with a pull out unit design. BCV: mixed flow, enclosed impeller, pre-fabricated concrete volute
BSV: mixed flow, open impeller, pre-fabricated concrete volute
BVOP: axial flow, pre-fabricated, concrete volute
BPV: axial flow, concrete casing
Between bearing centrifugal pumps
Commonly used in industry for various applications, one or several impellers on a shaft are suspended at both ends between two bearings. Types include dry pit , single and multistage, (double) volute, double suction impeller, axial split and foot mounted:
- HGT: horizontal
- VGT: vertical
Pump turbine combination
A prime example of ‘combined equipment’ is a pump-turbine that was designed, manufactured and installed by Stork in the Netherlands. During the rainy season the pump helps to keep feet dry. While in dry periods, it generates electricity as it allows water to flow back onto the backlands. Apart from being energy efficient, it's also operated at a low RPM in combination with a fish-friendly hydraulic design as per NEN 8775:2020. This allows fish to swim up/downstream during pumping and generating power.
Our extensive engineering department is highly experienced in developing fish-friendly pump hydraulics. These pumps are specified for atarget species of fish in the pumping area and are in compliance with standard NEN 8775:2020. These type of hydraulics are engineered from scratch for new build pumps as well as upgrading existing pumps. Our in-house developed fish passage can be fit in or next to the pumping station with an ecological efficiency of 90%.
