Vogelsang GL Series

The Gearless Rotary Lobe Pump – More Compact and Lightweight than Ever Before

The Vogelsang GL Series of Rotary Lobe Pumps are less weight and have smaller dimensions with the same performance – the new aluminum rotary lobe pump without a gearbox is a real space-saving miracle. The GL series weighs less than half as much as previous comparable rotary lobe pumps from Vogelsang and is an impressive 28 cm shorter thanks to the hydraulic motors, which are flanged directly in the housing – a decisive advantage for integration in tankers!

The range of pumps in the GL series is extremely diverse and meets a wide variety of needs. The design ensures reliable flow performance and a long service life, no matter how tough or aggressive the medium to be pumped may be or how high the throughput must be.

The GL 186 series is characterized by its sturdiness and power. As with the VX series, this gearless variant of the rotary lobe pump is just as powerful. The series is currently available in two different sizes. It is particular suitable for use in mobile applications where space is at a premium and a low unladen weight is required yet large quantities still have to be transported safely and reliably. Highly practical optional extras of the GL rotary lobe pump such as our tried-and-tested wear plates also mean they are suitable for applications where sturdiness is essential. At the same time, the pistons can be removed independently for even easier servicing.

 

Features:

  • Adjustable Pump Housing Segments:  On rotary lobe pumps from Vogelsang, wear on the pump housing segments is compensated without using additional parts. This makes the most of the material and prolongs service life.
  • Axial Wear Plates:  Axial wear plates are made from highly wear-resistant special steel and therefore extend maintenance intervals. They offer protection for the entire pump chamber and therefore not only simplify maintenance, but also minimize downtime. At the same time costs are minimized.
  • Quality Cartridge:  The Vogelsang Quality Cartridge stands for modern sealing technology. The mechanical seal in cartridge design is manufactured automatically in the factory, completely pre-assembled and checked by computer. This makes it quick and easy to change on site: assembly errors are avoided and the time required is reduced. This means quick and easy replacement of the shaft seal as well as safe commissioning after seal replacement.
  • Break-Proof Shafts:  GL pumps from Vogelsang have sturdy, break-proof shafts with a large diameter and without cranks and recesses to weaken them. The benefit is that Vogelsang rotary lobe pumps give a minimum shaft deflection even under high pressure, very low start-up wear, and ultimately reduced operating costs and spare parts costs.
  • Element-Based Design:  Vogelsang rotary lobe pumps are built according to a unique element-based design. With them, the customer isn’t forced to replace the entire body, but instead just the element that is affected. The economical replacement of individual components not only makes maintenance simpler and quicker, but simultaneously reduces the operating costs.

 

Options:

  • InjectionSystem:  The InjectionSystem significantly improves the foreign-matter resistance of the pump. It increases the efficiency and improves the suction capacity through optimized volumetric efficiency. Thanks to the InjectionSystem the service life of the pump is extended. Field trials prove a longer period of up to 2.5 times.
  • Radial Wear Plates:  The wear plates, made from highly wear-resistant special steel, extend maintenance intervals considerable, simplify maintenance and minimize downtimes. Also your costs are significantly reduce during maintenance.
  • HiFlo Lobes:  Unlike conventional lobes, Vogelsang’s HiFlo® lobes ensure pulsation-free pumping and consequently longer lifetimes for the drive and coupling. At the same time, the suction capacity is increased due to the higher number of sealing lines. The improved internal sealing enables suction from deep pits.
  • Speed Sensor:  The speed-dependent displacement of the VX rotary lobe pumps makes them ideal for precise longitudinal distribution within the spreading swath. Either screwed directly into the gearbox or in conjunction with the UDS both versions of the Vogelsang speed sensor are used to calculate the flow rate, allowing precise control of the required spreading capacity.
  • Aluminum Pump:  We offer another option which is perfectly suited to road transport: aluminum pump housing and lobe cores. This helps haulers to keep the tare of the transport vehicle to a minimum and thus increase the payload. The gearbox housing, bearing seal housing and QuickService cover are all made of aluminum. Particular attention has been paid to making sure that all components that come into contact with the medium are lined with robust gray cast iron or highly wear-resistant special steel.
