2BVA5110 Precision Cast Iron Liquid Ring Vacuum Pump (2.75 m³/min, 4 kW)

Designed for continuous chemical processing, pharmaceutical production, and heavy industrial dewatering, the GOFLEX 2BVA5110 (2BV5 110) Liquid Ring Vacuum Pump delivers a robust suction displacement of 2.75 m³/min (165 m³/h). Driven by a low-speed 1450 r.p.m., 4 kW motor and equipped with DN50 flanged connections, this 90 kg monoblock pump operates smoothly at ultra-low sound levels (≤63 dB(A)). Featuring a precision cast iron casing with optional SS304/SS316 stainless steel impellers, the 2BVA5110 achieves deep vacuum levels down to 33 mbar absolute (-0.097 MPa) while utilizing a 6.7 L/min liquid seal circulation for optimal heat dissipation and wet vapor handling.

Frequently Asked Questions (FAQ)

What are the core technical specifications of the 2BVA5110 vacuum pump?

The 2BVA5110 (2BV5 110) features a maximum air displacement of 2.75 m³/min (165 m³/h), a 4 kW motor running at 1450 r.p.m., DN50 flanged ports, 6.7 L/min liquid ring circulation, and reaches an ultimate limit vacuum of 33 mbar absolute (-0.097 MPa).

How does the 2BVA5110 (2BV5 series) differ from the 2BV2 series?

The 2BVA5110 belongs to the heavy-duty 2BV5 frame series operating at a slower 1450 r.p.m. motor speed for reduced wear, ultra-low noise (≤63 dB(A)), and standardized DN50 industrial flanged connections.

What material customization options are available for corrosive chemical duty?

While constructed with a robust precision cast iron body, the 2BVA5110 can be customized with SS304, SS316, or SS316L stainless steel impellers and flow components for aggressive chemical and pharmaceutical applications.

What operating liquid flow rate is required for the 2BVA5110?

The pump requires an operating liquid flow rate of 6.7 L/min to form the liquid seal ring, cool the mechanical seals, and absorb process heat during continuous duty.
