DVTLF 2.500

Becker DVTLF 2.500 – outdated model

The DVTLF 2.500 is neither in the Becker product range catalogue 01/2026 nor in Becker's product search; as combined dry-running pressure/vacuum pumps Becker today offers the T 4 and the DVT 3. Becker still publishes spare parts lists and service documents for the DVTLF. Becker names no successor. There is no combined pump of this size in the current range: the largest, the Becker DVT 3.140, draws 137 m³/h at 50 Hz. For vacuum duty alone, the Becker VTLF 2.500 (495 m³/h at 50 Hz) has the same frame size.

Technical data

According to the Becker data sheet of 18.02.2013, the DVTLF 2.500 draws 500 m³/h at 50 Hz and 575 m³/h at 60 Hz; vacuum and overpressure reach ±0.5 bar relative. The data sheet gives no absolute ultimate pressure; Becker gives the delivered air volume on request. Motor 15.0 kW at 50 Hz and 17.3 kW at 60 Hz; sound pressure level 80 / 82 dB(A) at 50 / 60 Hz; weight 420 kg. Width 747 mm, height 579 mm, length depending on the motor make; suction and pressure connection G 4", G 2" at the relief valves. An inlet filter and a pressure relief valve and a vacuum relief valve with silencer are built in; the DVTLF 2.500/0-69 also has a dust separator. Motor according to the data sheet: number 43479690300005GB, 15.0 kW at 50 Hz (400/690 V) and 17.3 kW at 60 Hz (460 V), 980 / 1180 min⁻¹, IP 55, IE2.

Pumping speed in combined operation

How much air the pump draws depends on the vacuum and the overpressure at the same time (suction air volume in m³/h according to the data sheet, reference 1000 mbar and 20 °C, tolerance ±5 %): For pumps in service, Ehrler & Beck supports you with service and with the selection of a current model.
