Product Overview
Oil Filtration Machine covers both stationary purification skids and compact service units, and the LYC-50A portable fine oil purifier is the classic workshop-grade model for hydraulic and lubrication oil servicing. Driven by a motor-coupled gear pump, the unit draws oil from drums or reservoirs through a 100 μm suction strainer, then passes it through a post-pump fine oil purifier cartridge available in 3.5, 10, 20 and 40 μm ratings. Rated flow is 50 L/min at 0.6 MPa working pressure, with original pressure loss held below 0.01 MPa. It is designed for three daily tasks: filtering new oil before filling, mobile bypass filtration of oil already in service, and periodic clean-up of small hydraulic reservoirs.

Workshop Application Scenario
This model is most frequently deployed in machine-tool and mould-making workshops where several small hydraulic power units share one service point. A maintenance technician moves the portable hydraulic oil filter machine between press, injection-moulding and machining centres, connecting the suction hose to the reservoir drain port and returning cleaned oil to the tank through the delivery hose. Two working patterns are typical: filtering a fresh drum of oil before it enters a sensitive servo valve circuit, and running a two-hour bypass loop on a machine that has just completed a repair, so that swarf and seal debris left in the pipework are removed before production restarts. Because the housing uses a quick-open cover, the secondary cartridge can be changed without tools, which keeps the unit in service during short maintenance windows.
Product Advantages
The gear-pump drive gives strong self-priming capability and low noise, allowing the unit to lift oil from underground tanks without an auxiliary priming pump. An overflow protection valve on the high-pressure line limits surge pressure when the operator closes the delivery valve too quickly, and a thermal relay protects the motor against overload on high-viscosity oil. Two filtration stages are arranged in series: the first retains coarse particles and protects the pump, while the second determines final cleanliness, so a single pass can already bring lightly contaminated oil back to a usable level. A panel-mounted pressure gauge continuously indicates cartridge loading, giving the operator a clear replacement signal instead of a fixed calendar interval.
Manufacturer & Factory Strength
Xinxiang Lifeierte Filter Corp., Ltd (Stock Code: 837936) has produced industrial oil filtration equipment for more than 15 years. Each LYC-50A unit is assembled, pressure-tested and flow-tested before dispatch, and the filter housings are verified against ISO 2941 collapse and burst requirements together with ISO 2942 fabrication integrity. Because the machine is built around standard cartridge dimensions, customers can source consumables from our replacement imported filter element range instead of returning the whole unit for service. Custom voltage, hose length and trolley configuration are accepted for workshop layouts where the standard 720 × 680 × 1020 mm footprint does not fit.
FAQ
Q1: Can the LYC-50A remove water from hydraulic oil?
A1: No. This model is a particulate fine oil purifier. Free water is only partly retained by the cartridge; for emulsified or dissolved water, a vacuum or coalescence dehydration unit is required.
Q2: What oil viscosity range can the pump handle?
A2: 10-160 cSt is recommended. Above 160 cSt the flow falls below the rated 50 L/min and motor load rises, so pre-heating is advised.
Q3: How often should the secondary cartridge be replaced?
A3: Replace when the panel gauge shows a clear rise over the clean baseline, or after the scheduled interval set by oil cleanliness monitoring. Severely contaminated oil shortens the interval sharply.
Q4: Is the unit suitable for phosphate ester fluid?
A4: Yes, with the V version specified for phosphate ester hydraulic fluid; seal and media compatibility must be confirmed at order stage.
Q5: Can it be used as a permanent online bypass unit?
A5: It is a mobile service unit. For continuous online bypass duty, a stationary purifier with fixed piping is more appropriate.
