Akal - Model VX215 -Powerful Rotary Lobe Pump
The VX215 series in the VX series has powerful capacities of up to 24,000 l/min or 1,417 m³/h and pressures of up to 8 bar. It is also very compact and has a low net weight. Another positive feature is its strong resistance to foreign substances thanks to its 90 mm wide free passage. This series can also be equipped with the InjectionSystem as an optional extra. This increases the pumps` insensitivity to foreign substances. To ensure rapid maintenance, the series is designed according to the QuickService principle. This means that all wet parts can be replaced in the installation position without disassembling the pump. This makes the VX215 series particularly well-suited for power-demanding pumping tasks, such as membrane filtration, tankers or self-propelled vehicles.
- Easy maintenance, fast on-site service thanks to access to the pumping chamber by simply removing the cover
- Cost-effective operation thanks to a high degree of efficiency
- Comprehensive range of features and options
- Self-priming, resistant to dry running and foreign objects
The rotary lobe pump is a positive displacement pump. The pumping principle is based on two counter-rotating pump elements known as rotary lobes. These are mounted on two synchronized shafts. The rotating movement of the lobes increases the volume of the pump chamber on the suction side. This creates suction that draws media into the rotary lobe pump. As the rotational motion continues, the medium is then sealed into the spaces between the rotating lobes and the pump casing and is again introduced to the discharge side by the pumping chambers as it reduces in size; The rotary lobe pump delivers the medium directly. Thanks to their mirror symmetrical design, rotary lobe pumps are independent of the direction of rotation and can pump in both directions without any restrictions. Developed in the 1990s, HiFlo lobes operate vibration-free, providing low vibration and extremely precise pumping.
- Open the cover:
Loosen the four nuts, remove the cover and you have free access to the pumping chamber. If necessary, you can also replace the cover`s wear plate at this stage. - Remove the swivel lobes:
Loosen the tension bolts, remove the pressure discs from the lobes, place the puller on the lobes and remove. - Remove the wear plates:
Once you have the lobes removed, all you have to do is unscrew the two screws and you can remove the wear plate from the gearbox. - Remove the quality Cartridge mechanical seal:
Using a simple pull-out device, you can now pull out the Cartridge mechanical seal and then replace it just as easily. - Assembly:
Fix the wear plate on the gearbox side with two screws, install the lobes and secure them to the shaft with the pressure discs, install the pump cover and screw it into place.
