When communicating with many customers, they all react that the price of Rotary Lobe Pump is several times higher than that of ordinary centrifugal pumps. However, the most critical reason for Rotary Lobe Pump to sell well in the market is the outstanding self-priming force and head performance, as well as a variety of different specifications and models of the product performance to better meet market demand.

Through the data statistics and analysis, rubber-coated rotor Rotary Lobe Pump strong self-priming, easy to maintain, low maintenance costs is the point of customer concern. In addition, the Rotary Lobe Pump has a compact structure, small shear force on the medium during transportation, smooth operation, low vibration, and a wide range of uses. Excellent performance in self-priming, vapor-liquid mixing, slurry transfer, etc.; particularly suitable for abrasive, high viscosity or pulsation-sensitive media.

Reasons why Rotary Lobe Pump sell well:

Replacement frequency

The comprehensive use of Rotary Lobe Pump low cost, on the one hand, reflected in the replacement frequency of wearing parts wearing parts are mainly rubber rotor, wear-resistant liner, assembled mechanical seal, seal.

Selection of the correct premise, 8 hours a day operation, from the data accumulated over the years, the main replacement of the rubber rotor and mechanical seals, time between 1.5 years -3 years, the price of these two parts of the overall price of the pump group is about 20%.

dry run capability

In operation, the rotor of the overflow chamber runs at low speed, the pump chamber forms a vacuum, the inlet forms a negative pressure, and the medium is sucked into the overflow chamber by the Rotary Lobe Pump to complete the conveying process.

Unlike centrifugal pumps, the mechanical seal of the Rotary Lobe Pump is cooled separately in the middle isolation chamber without contacting with the medium, so the Rotary Lobe Pump with rubber-coated rotor has the ability of dry running (with the medium in the overflow chamber).

replacement time

Rotary Lobe Pump are simple to replace wearing parts, and can be replaced by a single person following the instruction manual or video guide, with a simple rubber rotor replacement taking up to 25 minutes.

Floor space

In contrast, Rotary Lobe Pump have a smaller footprint, for example, instead of screw pumps, the original area where 2 pumps can be placed can be placed 3-4 Rotary Lobe Pump, making full use of civil space.
