DMG Bull PET piston booster — 3.5 and 4.0 MPa variants — Guangdong DMG Compressor (Foshan Nanhai)

Datasheet

Product overview

Power: LGJ-4:45 installed /41 shaft kW · Pressure: 3.5 MPa LGJ;4.0 MPa LGV · Flow: Selected paired duties:4–12 Nm³/min

Bull is DMG's multistage PET selection with a double-acting piston booster. The manufacturer describes stainless air/water lines, skid installation and a common panel with fault diagnosis. Variable-frequency and permanent-magnet options need the exact supplied motor, drive, control and protection details rather than an assumed configuration from a family title.

The model table separates 3.5 MPa LGJ/35TS and 4.0 MPa LGV/40 duties. LGJ-4.0/35TS (PM) gives 4.0 Nm³/min at 3.5 MPa, 45 kW installed and 41 kW shaft, 620 rpm, 1800 kg, 15 t/h circulating water and 2400 × 1350 × 1850 mm. LGJ-6.0/35TS (PM) gives 6.0 Nm³/min at 3.5 MPa, 67/60 kW installed/shaft, 530 rpm, 2200 kg, 20 t/h and the same size. Both show DN40 exhaust and a separate 1½-inch inlet/outlet diameter entry.

At 4.0 MPa, LGV-6.0/40 (PM) gives 6.0 Nm³/min, 67/60 kW, 530 rpm, 2480 kg, 20 t/h and 2800 × 1500 × 1500 mm. LGV-8.0/40 PM gives 8.0 Nm³/min, 85/77 kW, 580 rpm, 2438 kg and 25 t/h, with the same published size. LGV-12/40 (PM) lists 12 Nm³/min, 135/122 kW, 520 rpm, 4000 kg, 40 t/h and 3100 × 1850 × 1770 mm. All selected rows show DN40 exhaust. These model duties do not establish a continuous 3.5–4.0 MPa performance envelope for one unit.

The unusual lower published mass of the 8.0 row compared with the 6.0 row is retained as table data, not silently corrected; obtain the current lifting and foundation drawing. Installed and shaft ratings do not establish measured input or savings. Specify the production-cycle duty and volume reference, pressure loss, receiver and recovery arrangement. Confirm the air/lubrication/cooling circuit boundaries, cooling-water quantity/temperature/quality, drains, dryer/filter scope, safety and control interfaces and access to valves, rings and packing. Agree air-purity sampling, model-specific reports, current drawings, tests, wear-part intervals, warranty and destination commissioning/support. The original image shows a complete Bull family package, without identifying a particular table model.
