Flux Pumps are experts in manufacturing vertical pumps. Having created the world’s first vertical electric drum pump in 1950, we now have over 75 years of expertise in the production of vertical chemical pumps.
Our F 600 series vertical pumps deliver exceptional performance in heavy-duty circulation and tank transfer applications. Designed predominantly for stationary use, these centrifugal immersion pumps are ideal for transferring large volumes of potentially hazardous, or abrasive liquids. Furthermore, with immersion lengths ranging from 300 mm to 4100 mm (depending on material), these pumps are suitable for closed tanks, open basins, IBCs and more.
Importantly, all F 600 series vertical pumps utilise a ceramic-oxide mechanical shaft seal, for reliable, efficient transfer of abrasive, or solids-laden fluids. The design consists of an inner and outer tube, with the driveshaft supported by intermediate bearings within the inner tube. The mechanical seal isolates the bearings and shaft from the pumped fluid. These pumps are powered by a range of 3-phase electric motors.
Flux manufactures F 620 models from stainless steel, in lengths up to 3,000 mm. These pumps utilise a conical open impeller (for improved solids handling), delivering a maximum flow rate of 23 m³/hr and a maximum delivery head of 12 mwc.
Furthermore, F 640 models are available in polypropylene and PVDF, with a choice of conical open or closed centrifugal impellers, delivering up to 42 m3/hr and max delivery head 32 mwc. In addition, F 640 pumps utilise the unique Flux steel-cored inner tube, for optimal strength, stability at high temperatures and extended service life.
These high flow pumps are suitable for many industrial applications, such as transferring corrosive liquids, acids and bases in chemical waste processing, biogas treatment, electroplating, sump or pit emptying, PCB manufacturing and water & wastewater treatment. Choose Flux for demanding tasks – F 600 series vertical immersion pumps provide the power and durability needed to get the job done.
Flux designed the F 620 vertical stainless steel tank pump to transfer and circulate a range of low- to medium-viscosity liquids up to 2,500 mPas. Two designs are available, the standard vertical model and the horizontal TR model. Notably, F 620 is available only with an open conical impeller in two diameters (15 or 30 size). Therefore, this pump can deliver reliable performance even with challenging, solids-laden media.

Flux designed the F 640 PP 15 / 30 Z pumps to pump and circulate low- to medium-viscosity liquids up to 2,500 mPas (when fitted with a conical impeller). Two designs are available, the standard vertical model and the horizontal TR model. Available with a choice of four impellers – 15 or 30 open conical rotor (for improved solids handling), or 15 Z or 30 Z closed centrifugal impeller (for higher flow and delivery pressure with pure liquids), the F 640 PP 15 / 30 Z is available with motors from 0.75 to 2 kW.
F 640 models are larger pumps, designed for high-flow pumping and circulation of low- to medium-viscosity abrasive liquids, up to 150 mPas. Once again, two designs are available, standard vertical models and horizontal TR models. We offer these pumps in both polypropylene and PVDF materials (TR only in PP), with a choice of two impeller sizes – 185 or 230, both featuring a closed centrifugal impeller design. Furthermore, the F 640 185 / 230 is available with motors from 0.75 kW up to 4 kW.
A vertical pump is inserted directly into a tank, drum, vessel, or chamber opening. The liquid inlet is at the tip of the vertical pump tube. Consequently, the pump inlet is almost always completely submerged at the bottom of the container.
A complete vertical pump consists of a drive motor and pump (known as the pump tube, lance, wand, stick or immersion pump). Larger vertical pumps are produced with a mounting flange (for bolting the pump to a tank lid) and accessories such as lifting handles. Additionally, drive motors are flange-mount designs that bolt to a mating flange on top of the pump tube. Therefore, drive motors sit outside the vessel to be emptied.
Note that vertical pumps are available in three common types: centrifugal, progressive cavity and piston designs. Centrifugal vertical pumps contain a driveshaft, supported by a series of intermediate bearings and a lower bearing housing that supports the impeller, which consequently spins at high speeds. Furthermore, these pumps are available with or without a mechanical seal, and are suitable for handling low to medium viscosity liquids. They deliver comparatively high flow rates, compared to progressive cavity and piston pump designs.
Use vertical progressive cavity and piston type positive displacement pumps to transfer high-viscosity, or adhesive media. They can generate very high discharge pressure, required to move difficult, sticky media. Furthermore, the fully immersed fluid inlet helps liquid to flow into the pump chamber, thereby making vertical pumps an efficient choice for high viscosity pumping applications.
Flux Pumps is a world leader in vertical pump production. With 75 years of experience, German engineering quality and unique design features, rely on Flux for your process pumping requirements.
While vertical pumps offer many advantages, there are some disadvantages:
The primary difference between horizontal and vertical pumps is the orientation of the pump shaft:
Vertical pumps
Firstly, vertical pumps have a vertical driveshaft and top-mounted motor, making them ideal for direct installation in confined spaces, tanks and basins with limited access. These pumps are efficient, because the pump inlet is immersed directly in the fluid. Therefore, liquid flows to the pump inlet without any pressure losses associated with inlet pipework.
They are particularly useful for tank transfer, filtration and separation applications where large liquid volumes need to be transferred or circulated. However, they tend to be more expensive than horizontal designs, as they contain considerably more material. Generally, vertical pumps tend to be used in chemical transfer and waste handling applications.
Horizontal pumps
Horizontal pumps, on the other hand, have a horizontally mounted shaft and motor, They are often mounted on a baseplate, or bolted directly to a suitable level surface. Notably, they are the most common pump type, used in a huge range of applications for pumping almost any low-viscosity fluid.
Furthermore, horizontal pumps are connected to the liquid supply vessel via inlet pipework, or hose. If the pump is installed below the liquid level, the force of gravity and atmospheric pressure will help to push fluid to the pump inlet. Therefore, overly long, or restrictive inlet pipework should be avoided to maintain pump efficiency. Conversely, if the pump is installed above the liquid level, the pump must be a self-priming design (or possibly a manually-primed design), so the pump can draw fluid vertically upwards to the inlet. Horizontal pumps are generally more compact, easier to install and maintain compared to vertical pumps.
Vertical pumps are generally better suited for high-lift, chemical processing applications where efficiency is a key requirement, whereas horizontal pumps are better for general fluid transport where purchase cost is a key factor.
