In industrial environments, lubricant cleanliness directly impacts machinery lifetime. Built for versatile offline filtration, the DES-CASE Filter Cart offers reliability professionals a portable, heavy-duty solution for decontaminating systems, flushing new or repaired equipment, and pre-filtering new oils. This comprehensive technical guide covers the performance specs, customizable options, and practical maintenance considerations of this workhorse unit.
What are the operating limits of the DES-CASE Filter Cart?
The DES-CASE Filter Cart is engineered to filter mineral-based industrial oils and most synthetic oils. It handles fluids with a maximum operating viscosity range of ISO VG 680 (3000ssu / 648cSt) at 100°F (38°C). Operating outside this range can reduce pump efficiency or bypass the filters entirely.
The system is designed for extreme plant environments, operating within an ambient temperature range of -15°F to 150°F (-26°C to 66°C). The structural elements include a carbon steel frame, industrial powder coat paint, aluminum filter heads, and zinc-plated steel or brass fittings. Standard gaskets are constructed from Buna-N, though Viton options can be specified for chemical compatibility.
How does dual-stage filtration protect downstream machinery?
Dual-stage filtration processes the oil through two successive filters to maximize particulate and moisture extraction. The cart features a standard pre-filter and a post-filter setup (Filter Element A and Filter Element B) to sequence contaminant removal. This dual design prevents premature loading of high-efficiency elements by catching larger particulates first.
The filter heads include integrated differential indicators. A filter indicator pops at 22psid (1.55 bar) to provide a clear mechanical warning that the filter elements are loaded and require replacement. To protect the motor and pump from over-pressure conditions, the internal pump relief valve is set to open at 65psi.
What pump and motor options can you select?
The system can be configured with multiple electrical or pneumatic drive systems. For standard electrical grids, DES-CASE offers 60Hz and 50Hz motor options. The 60Hz options range from 2gpm to 10gpm pump capacities paired with 1hp electric motors running at 1725 rpm on either 115vac (13 amps) or 230vac (6.5 amps). The 50Hz options provide flow rates of 1.5gpm to 8gpm using 1hp electric motors running at 1425 rpm on 110vac (12.4 amps) or 220vac (6.2 amps).
For applications where electricity is unavailable or restricted, pneumatic options can be selected. These include a 2gpm or 8gpm pump paired with a 1.7hp air motor operating from 0 to 3000 rpm. All pump and motor configurations utilize a robust internal gear pump design to manage high-viscosity industrial fluids.
How do connection sizes affect filtration performance?
While hose connections are highly customizable, sizing directly impacts flow dynamics. Standard configurations are optimized for performance when using a 1-inch suction hose (drain) and a 3/4-inch pressure hose (fill). Using smaller connector configurations can restrict flow and cause a drop in performance, though the physical hoses remain 1-inch and 3/4-inch respectively.
Available connection types include ISO B, ISO A, and Flush Face quick connectors. These can be configured in standard or BSPP threads. To facilitate fluid health monitoring, the cart can be customized with pre-filter and post-filter sample valves, including standard Minimess or high-viscosity push-button style valves.
Summary
- Viscosity Limit: Filters mineral and synthetic oils up to ISO VG 680 (3000ssu/648cSt) at 100°F/38°C.
- System Pressure: Filter indicators pop at 22psid to signal element replacement, while pump relief opens at 65psi.
- Dual-Stage Elements: Utilizes high-efficiency media rated at Beta 200 at 3, 6, 12, or 25 microns, alongside water removal options.
- Connection Warning: Optimum performance requires a 1-inch drain connection and a 3/4-inch fill connection to prevent flow restriction.
Step-by-step
- Verify that the fluid viscosity does not exceed the ISO VG 680 limit at operating temperature.
- Connect the 12-foot suction hose (drain) and pressure hose (fill) to the appropriate mating adapters on the reservoir.
- Plug in the 25-foot electrical cord to a matching power source, or connect the air supply line for pneumatic motors.
- Monitor the pressure gauge and filter indicators during operation to ensure the pressure does not trigger the 22psid filter change warning.
- Draw fluid samples from the pre-filter or post-filter sample valves to analyze clean-up progress.
- Disconnect the hoses and store them in the integrated cart oil catch pan to prevent environmental spills.
