Waterjet-Parts-05049689-Oil-filter-intensifier-pump.334.3-1
Product Name: Hydraulic Oil Filter Element / Spin-On Filter (6 Micron) – Part No. 05049689
Description:
This component is a spin-on hydraulic oil filter element with a 6-micron filtration rating, specifically designed for the hydraulic reservoir in waterjet intensifier pumps . The "6 micron" rating indicates this element is capable of removing fine particulate contaminants, including metal wear debris, dirt, and sludge, from the hydraulic oil. The filter features a spin-on design for easy replacement and is constructed with multi-layer microglass or stainless-steel mesh media for high dirt-holding capacity and low pressure drop .
This filter element is a standard component in the hydraulic reservoir assembly (Reservoir Assembly 72152878) of waterjet cutting systems . It is installed on the hydraulic filter head and serves as the primary filtration device for the hydraulic circuit.
Applications:
Primary filtration for hydraulic fluid in waterjet intensifier pumps and hydraulic reservoirs
Removes fine contaminants (down to 6 microns) to protect intensifier seals, valves, and precision components
Protects hydraulic pump and intensifier from contamination-induced wear
Compatible with KMT waterjet intensifier pumps including NeoLine, SL-IV, and SL-V series (15–60 HP)
Suitable for general industrial oil circulation systems requiring 6-micron filtration
Features:
Filtration Rating: 6 microns absolute/nominal for fine particle removal
Spin-On Design: Easy, tool-free replacement; simply unscrew the old element and screw on the new one
High-Performance Media: Multi-layer microglass or stainless-steel mesh construction offers high contaminant capacity and low flow restriction
Durable Construction: Corrosion-resistant core and end caps withstand high flow rates and elevated temperatures
Standard Size: 4.0-inch diameter spin-on configuration
OEM Compatibility: Direct replacement for KMT #05049689 ; cross-reference part numbers: 5000041, 103378
Maintenance:
Failure Diagnosis (When to Replace):
Clogging Indicator: When the filter's signal light illuminates or the differential pressure gauge indicates a blockage, the element requires immediate replacement
Scheduled Replacement: According to manufacturer recommendations, hydraulic oil and filters should be replaced every 1,000–3,000 operating hours or at least once per year . Some manufacturers recommend replacement every 500 hours for high-pressure systems
Hydraulic Performance Issues: Slow intensifier cycling, difficulty building pressure, or unusual pump noise may indicate a clogged filter restricting oil flow
Fluid Contamination: If oil analysis shows high particle counts or the oil appears dark or hazy, inspect and replace the filter
Post-Overhaul Replacement: After any major pump repair or component failure, replace the filter element to remove debris introduced during service
Replacement Guidelines:
Full Depressurization (Critical): Before any maintenance, place the main electrical disconnect in the OFF position, fully depressurize the hydraulic system, and follow lockout/tagout procedures
Clean Mounting Surface: Wipe the filter head's sealing surface clean before installing the new element to prevent debris ingress
Lubricate Seal: Apply a thin film of clean hydraulic oil to the O-ring seal on the new filter element to ensure proper seating and prevent tearing during installation
Hand Tighten Only: Spin the new filter onto the head until the gasket contacts the sealing surface, then tighten an additional 1/2 to 3/4 turn by hand. Do not use a wrench to over-tighten, as this can damage the seal or filter head
Check for Leaks: After installation, run the hydraulic system and inspect the filter head for any signs of external oil leakage
Proper Disposal: Dispose of the used filter in accordance with local environmental regulations
Oil Change Interval: When replacing the filter, it is recommended to also change the hydraulic oil per the manufacturer's schedule. The oil tank should be cleaned every six months
