18.5 kW Rotary lobe pump has strong self-priming force and high head force, the design is completely symmetrical, the conveying direction can be changed by changing the driving direction, non-clogging, strong impurities through the capacity.

Precautions for selection of rotary lobe pump

1. Shaft power = flow Q (m³/h) x head H (Bar) / 36 / η.
2. When the conveying medium is clear water, sewage and relatively dilute mud, the rotational speed n≤350rpm, when the conveying medium is dry mud, the rotational speed n≤100rpm.
3. When it is necessary to ensure the self-priming height, the speed n is greater than or equal to 200rpm, when the equipment is running with gaps, such as mobile pump trucks, the speed can be greater than 350rpm.
4. Different environments, different media, different speeds, please contact RDDLZ technicians.
5. Other power lobe rotary lobe pumps can be customized.

Feature

• Strong self-priming ability, often used to replace submersible pumps or submersible pumps, the maximum suction stroke of the pump can reach 8.5-9.5 meters.
• The lobe pump has good wear resistance and is often used to transport fluid media containing impurities such as sludge, sewage, and slag.
• Simple maintenance, no need to dismantle the pipeline.
• Reversible operation, the design is completely symmetrical, and the conveying direction can be changed by changing the driving direction.
• No blockage, strong ability to pass impurities.
• Idling/dry running: the pump is insensitive to dry running, and short-term running will not cause damage to the pump.
• Energy saving and electricity saving, high efficiency.
• To solve the gas resistance, it can be mixed and conveyed with gas, liquid and slag.
• The overall operating cost of the pump is low.
• Ultra-wide medium viscosity conveying range, from low viscosity medium to high viscosity medium can be smoothly conveyed.

Lobe Pump Applications

Tips: Rotary lobe pump structure

The design of RDDLZ Rotary lobe pump is very simple. All pumps are composed of pump cavity and gear cavity. The design of pump cavity is particularly simple. All models of lobe pumps retain a simple design style. Without dismantling the pipeline, the driver can maintain on-line by himself, which provides a guarantee. The downtime is greatly reduced, and the design of the all-round wear-resistant lining plate, front and rear, up and down, ensures the wear of the pump casing in all directions and ensures long-term durability. Such simple maintenance features reduce the cost of the entire operating cycle of the equipment.
