Frequently Asked Questions (FAQ)

What are the key technical specifications of the 2BVA5111 vacuum pump?

The 2BVA5111 (2BV5 111) features a maximum air suction capacity of 3.83 m³/min (229.8 m³/h), a 5.5 kW motor operating at 1450 r.p.m., DN50 flanged connections, an 8.3 L/min liquid ring flow rate, and achieves an ultimate limit vacuum of 33 mbar absolute (-0.097 MPa).

How does the 2BVA5111 compare to the 2BVA5110 model?

The 2BVA5111 delivers nearly 40% higher displacement capacity (3.83 m³/min vs 2.75 m³/min) using a 5.5 kW motor, making it better optimized for larger industrial vacuum filtration, distillation, and heavy-duty dewatering systems.

What material customization options are available for aggressive chemical applications?

Constructed with a heavy-duty precision cast iron frame and standard mechanical seals, the 2BVA5111 offers options for SS304, SS316, or SS316L stainless steel impellers and flow paths to handle corrosive process gases.

What is the liquid seal circulation requirement for the 2BVA5111?

The pump requires an 8.3 L/min continuous operating liquid supply to maintain the sealing water ring, cool internal mechanical components, and dissipate process heat under continuous duty.
