The Bomag 07993999 Differential Pressure Switch is a genuine OEM component designed for a wide range of Bomag tandem rollers, single drum rollers, refuse/landfill compactors, and the MPH 121 recycler/stabilizer. Sourced directly from Bomag, this switch delivers an exact match to the original specification, ensuring correct system readings and dependable operation. Compatible machines include BW 184 AD tandem rollers, BW 213 D-3 and BW 177 D-3 single drum rollers, BC 601 RB, BC 671 RS, BC 771 RB refuse/landfill compactors, and many additional BW and BC models across the lineup.
Key Features
- Genuine OEM Pressure Sensing Accuracy — manufactured to Bomag's original switching thresholds, ensuring the hydraulic or filter system is monitored at the correct differential values — not approximated.
- Direct-Swap Replacement — matches the original connector, thread, and port configuration for a straightforward installation with no alterations to existing lines or harnesses.
- Broad Bomag Fleet Coverage — fits BW-series tandem rollers including the BW 170 AD, BW 174 AD, and BW 184 AD; BW-series single drum rollers including BW 177, BW 212, BW 213, BW 214, BW 216, BW 219, BW 225, and C 850 C; BC-series refuse/landfill compactors including the BC 570 RB, BC 601 RB, BC 601 RS, BC 670 RB, BC 671 RS, BC 672 RB, BC 771 RB, and BC 571 RB; the BW 27 RH pneumatic tyred roller; and the MPH 121 recycler/stabilizer.
- Protects Critical Machine Systems — a correctly functioning differential pressure switch alerts operators to rising pressure differentials across filters or hydraulic circuits before damage occurs; a failed switch can mask blockages, risking component wear or system failure.
- Electrical Integrity — OEM-spec switching contacts and housing ratings maintain reliable signal output to the machine's control system, preventing false alarms or missed warnings that a lower-grade substitute might introduce.
A differential pressure switch monitors the pressure difference across a component — typically a hydraulic filter or fluid circuit — and triggers a warning signal when that difference exceeds a set threshold, indicating a restriction or blockage. On Bomag compaction and soil-processing equipment, this alert prompts timely maintenance before restricted flow causes overheating, reduced hydraulic performance, or accelerated wear on downstream components. When the switch fails or reads inaccurately, the machine's monitoring system loses a critical input, leaving operators without early warning of a developing fault.
