Product Introduction
The LPFC series portable oil purifier trolley is a mobile hydraulic filtration unit engineered for on-site oil treatment. Equipped with a motor-driven gear pump, overflow protection circuit and quick-open filter housing, this hydraulic filter trolley delivers low-noise operation, strong self-priming capacity and convenient element replacement without extra tools. It is widely adopted for filtering fresh oil, charging clean oil, purifying in-service fluid and running bypass filtration while hydraulic lubrication systems keep operating. Multiple model options cover flow from 25 L/min up to 400 L/min, with customizable filtration precision to match different cleanliness requirements of industrial fluid systems.
Working Principle
When the LPFC oil purifier starts, the gear pump draws contaminated oil through the suction-side coarse filter, which captures large particles to protect the pump assembly. The oil then flows into the fine filter cartridge inside the main filter housing. Solid particles are trapped by the filter medium, while cleaned oil discharges out to the oil tank or hydraulic loop. A built-in pressure gauge monitors differential pressure continuously to indicate filter element clogging status. The overflow valve provides pressure relief, and thermal relay protection cuts power automatically to avoid motor overload damage. Operators can open the quick-cover filter housing directly for fast cartridge replacement once the pressure difference reaches the preset threshold.

FAQ
Q1: What viscosity of oil can this LPFC oil purifier handle?
A: Different LPFC models support different viscosity ranges. Standard models adapt to medium viscosity ≤100 cSt, YV versions support up to 700 cSt, and the 400 flow model supports ≤260 cSt.
Q2: Can I change the filtration precision freely?
A: Yes. You can swap fine filter cartridges of different micron ratings to adjust filtration precision according to your target oil cleanliness requirement.
Q3: Does this purifier work for fire-resistant hydraulic fluid?
A: Yes. It is compatible with water-glycol and phosphate ester fire-resistant fluids besides regular mineral hydraulic oil.
Q4: How to judge when the filter element needs replacement?
A: Check the pressure gauge. When the differential pressure rises to the specified value, it means the filter cartridge is blocked and needs replacement.
Q5: Is this LPFC series a replacement option for imported oil filter trolley?
A: Yes, the LPFC series is developed as a cost-effective alternative solution, with matched flow, pressure and filtration performance for on-site oil purification.
