Equipped with a honeycomb damping housing and floating piston design, the plunger achieves a noise level of ≤62dB(A) at 1-meter distance—35% lower than standard metal plungers. This makes it suitable for noise-sensitive environments such as indoor maintenance workshops and residential-area service stations .
The ceramic plunger surface features a Ra 0.02μm polished finish, reducing friction by 40% compared to stainless steel alternatives. Under typical operating conditions (150bar pressure, 18L/min flow), its service life exceeds 5,000 working hours—twice the industry average .
The plunger’s variable displacement mechanism adjusts oil flow based on contamination levels, reducing diesel engine load by 12-15% during light-duty cleaning. This translates to 0.8L/h lower fuel consumption for compatible washers .
The Sophisticated Low Noise Diesel Engine Washer Oil Cleaning Plunger is a precision-engineered component designed for high-efficiency oil contamination removal in diesel-powered cleaning systems. Integrating advanced hydraulic technology with noise-reduction engineering, this plunger serves as the core of oil cleaning modules, compatible with most industrial diesel engine washers ranging from 10HP to 25HP. Its main body adopts 99.5% alumina ceramic material, which resists corrosion from mineral oil, synthetic oil, and diesel fuel blends, while the sealing system uses fluoropolymer rings tested to withstand continuous operation at temperatures up to 120°C . Unlike conventional plungers, it incorporates a multi-stage filtration structure that captures particles as small as 5μm, ensuring cleaned oil meets ISO 4406 Class 16/14/11 purity standards.
Ideal for cleaning lubrication systems of construction machinery (excavators, loaders) and stationary diesel generators, removing carbon deposits and metal shavings that cause component wear .
Used in truck and bus maintenance facilities to restore oil performance in engine crankcases and transmission systems, extending oil change intervals by 30% .
Suitable for shipboard diesel engine oil cleaning, with corrosion-resistant materials that withstand high-humidity, salt-laden environments .
Q: What power source does the RTD-250 Unit require?
A: It operates on 3-phase 380V/50Hz or 460V/60Hz power, with a rated motor power of 250 hp (186 kW) for consistent performance .
Q: Can it handle hot water applications?
A: Yes, it supports fluid temperatures up to 80 °C (176 °F) , making it ideal for degreasing tasks in food processing facilities .
Q: How long does routine maintenance take?
A: Basic maintenance (filter replacement, oil check) takes less than 30 minutes, while plunger packing replacement requires 90 minutes with the quick-access service panel .
