Flowrox™ LPP-T transfer pumps

Optimized for demanding slurry transfer

Flowrox LPP-T transfer pumps incorporate advanced single roller design which eliminates friction and lowers energy consumption. They are ideal for pumping various slurries and dosing a wide range of abrasive, corrosive, viscous or crystallizing media.

Low operating costs

Advanced single roller design eliminates friction and lowers energy consumption.

Capability to pump 24/7

No overheating at high continuous flow rates due to the roller design that minimizes friction and heat.

Pumps high solid content slurries

The pump design allows pumping slurries with up to 60-80% solids content.

Long service intervals & ease of maintenance

Pump hose is the only replaceable part and can be easily changed on site.

No mixing or shearing of the medium

Enabled by the peristaltic effect.

Advanced rolling design

The operating principle of the Flowrox hose pumps is based on the peristaltic effect. As the cylindrical rotor rotates along the hose, the process medium gets pushed forward through the hose. At the same time, the hose behind the compression point reverts to its original circular shape creating a suction effect at the pump inlet port. As a result, the hose bore is re-filled with the medium. No backward flow or slip can occur as the hose is squeezed tight by the roller.

Due to their technical features, Flowrox hose pumps provide exact flow per revolution. They also incorporate an advanced rolling design, which eliminates friction, maximizes hose life and lowers energy consumption. Energy efficiency, long hose life and low maintenance generates substantial savings during the life cycle of peristaltic pumps. Lifetime of Flowrox pumps’ hoses is 3-5 times longer than conventional hose pumps.

Trailblazing peristaltic pump technology

Flowrox LPP-T transfer pumps are equipped with a patented hose flange and reliable in-line pipe connections, as well as a hose leak detection unit. Patented adjustment mechanism senses hose wear when compression is readjusted. This helps to maximize hose lifetime and minimize the risk of over-compression. There is no need for shimming. The LPP-T100 is one of the world’s largest hose pumps, with a maximum continuous flow of 100 m³/h.

Pumping 76% rock solids with Flowrox™ hose pumps

LKAB Svappavaara iron ore mine in Sweden chose Flowrox LPP-T100 transfer pumps for their pelletizing plant. They were looking for a solution that would allow them to pump effectively paste and high-density slurries. "The most important thing in terms of pump performance is that they function reliably. All the other benefits come after that. If a pump is not reliable, there is nothing else to benefit from either", the customer states.

Steady and reliable feed ensured at a chemical plant in Germany with Flowrox pumps

CURRENTA is managing and providing services to CHEMPARK in Leverkusen, Germany. All of its hazardous waste incineration plants were using conventional filter presses to separate solids from waste water generated by flue-gas scrubbing. In 2009, CURRENTA started a modernization project to replace the existing filter press installations. Nowadays, Flowrox™ LPP-T peristaltic pumps feed fully automatic filter presses for flue-gas scrubbing process in this German chemical plant.

Rubber hose solves scaling issue -Increased uptime and process efficiency with Flowrox pumps

A smelting plant in Norway had a scaling problem. Their spill process water contains lots of carbonates which caused reoccurring damage to the previously used centrifugal pump. Another challenge for the new pump was to also empty the 3-meter-deep tank located underneath the pump’s location.

What makes single rolling design peristaltic pumps the best solution when pumping abrasive slurries?

The superintendent of the water treatment plant was examining shoe designed peristaltic pumps and single rolling design peristaltic pumps. The customer was convinced that Flowrox's peristaltic pump with only one compression per 360 degree revolution will lead to at least 3-5 times longer hose life time than conventional hose pumps. After installation, the first hoses in the Flowrox pumps lasted approximately for 9 months - a great result with 11 million revolutions while pumping abrasive lime.
