Bomag 07993992 Differential Pressure Switch

The Bomag 07993992 Differential Pressure Switch is a genuine OEM component designed for a wide range of Bomag equipment, including BF-series pavers, BM-series cold milling machines, BW-series single drum, tandem, and pneumatic tyred rollers, BC-series refuse/landfill and soil compactors, MPH- and RS-series recyclers/stabilizers, and C-series single drum rollers. This switch ships directly from authorized Bomag OEM supply, ensuring the exact fit and specification your machine calls for. Sourced as a genuine OEM part, it meets the same standards as the component originally installed on your equipment. Compatible models span a broad cross-section of the Bomag line, from BF 300 P and BF 800 C pavers to BM 500/15 and BM 2000/60 cold milling machines, BW 124, BW 177, BW 213, and BW 226 single drum rollers, BW 141, BW 161, and BW 202 tandem rollers, BC 472 RB through BC 1172 RB refuse/landfill compactors, BC 462 EB and BC 772 EB-2 soil compactors, MPH 121, MPH 122, and MPH 600 recyclers/stabilizers, and RS 460, RS 500, and RS 650 recyclers/stabilizers, among many others — confirming this switch's role as a shared OEM component across the Bomag fleet.

Key Features

• Genuine OEM Sensing Accuracy — Manufactured to Bomag's original pressure-differential specification, this switch activates at the exact threshold your machine's hydraulic or fluid system is engineered around, avoiding nuisance trips or missed fault conditions that off-spec switches can cause.
• Drop-In Electrical and Port Fit — Matching OEM connector geometry and thread specification, this switch installs directly in place of the original without re-wiring or port modification.
• Broad Fleet Coverage — Fits pavers including BF 300 P and BF 800 C variants, cold milling machines including BM 500/15 and BM 2000/60, single drum rollers including BW 213, BW 216, BW 219, and BW 226 models, tandem rollers including BW 141, BW 161, and BW 202 models, pneumatic tyred rollers including BW 24 RH, BW 25 RH, BW 27 RH, and BW 28 RH, BC-series refuse/landfill and soil compactors, and MPH- and RS-series recyclers/stabilizers — making it a high-utility stocking part across a mixed Bomag fleet.
• System Protection Through Reliable Switching — A correctly functioning differential pressure switch signals filter restriction, flow loss, or circuit pressure imbalance before damage occurs. A failed or sluggish switch allows a machine to run in a degraded state, risking component damage to hydraulic pumps, motors, or filtration systems.
• Electrical Safety Integrity — As a switching component in the machine's monitoring circuit, correct resistance and contact rating are critical. The genuine OEM part maintains the designed electrical characteristics, preventing false signals or open-circuit faults that could mask real system warnings.

A differential pressure switch monitors the pressure difference across two points in a fluid or hydraulic circuit — most commonly across a filter element or between two sides of a flow path. When that pressure difference rises above the designed threshold (indicating a clogged filter or restricted flow, for example), the switch changes state and sends a signal to the machine's control system or warning indicator. This alerts the operator or triggers a protective response before the restriction causes starvation or overheating damage downstream. When this switch fails or reads inaccurately, the machine either loses the ability to detect a real problem or generates false warnings that disrupt operation — both outcomes that affect machine reliability and service intervals.
