About LENZ

LENZ is a manufacturer of hydraulic accessories and fluid power components, with a product line that includes tank suction strainers, return line filters, replacement elements, and oil level gauges. The brand is known for components that protect hydraulic pumps and systems by filtering contaminants from hydraulic fluid and providing visual indication of fluid levels and temperatures. LENZ products are used in industrial, mobile, and marine hydraulic systems where reliable filtration and fluid monitoring are required. 3G Electric supplies the LENZ line to plant engineers, maintenance managers, and procurement specialists worldwide, offering individual components as well as replacement parts to support maintenance and repair operations.

The LENZ product range covers several key categories. Hydraulic tank suction strainers are available in various flow capacities, including 10 gpm, 15 gpm, 25 gpm, 30 gpm, and 50 gpm, with connection sizes from 3/4 in NPT to 2 in NPT. These strainers feature 100 mesh stainless steel elements and are designed for either internal or external mounting on hydraulic reservoirs. The stainless steel construction provides corrosion resistance and durability in demanding environments. Oil level gauges for unpressurized tanks include models with 1/2"-13 threads, 5 in mounting centers, and 5.9 in body height, often with integrated thermometers for temperature indication. These gauges use Buna N seals rated to 212°F and are suitable for direct reading of fluid level and temperature.

Technical buyers should note that LENZ components are specified by flow rate, connection type, mesh size, and mounting configuration. For example, the suction strainers are identified by their flow capacity and whether they are externally mounted or designed for internal tank installation. The 100 mesh stainless steel elements provide filtration down to 149 microns, protecting pumps from particulate contamination. The oil level gauges are designed for unpressurized tanks and include a thermometer for monitoring fluid temperature, which can help identify overheating conditions. These specifications allow engineers to select the appropriate component for their hydraulic system requirements.

3G Electric supports the LENZ line by maintaining inventory of popular models and providing application assistance to help customers match the correct strainer or gauge to their system. The company serves a global customer base, shipping to various regions and supporting maintenance, repair, and operations (MRO) as well as original equipment manufacturing (OEM) needs. With a focus on technical accuracy and product availability, 3G Electric aims to be a reliable source for LENZ hydraulic components. For specific part numbers, flow rates, or connection sizes, customers can contact 3G Electric for a quote and lead time information.

Common Applications

  • Industrial hydraulic power units — LENZ tank suction strainers (e.g., MPN 221206, 30 gpm, 1 1/2 in NPT) protect pumps from particulate contamination in reservoir suction lines.
  • Mobile hydraulic systems — LENZ externally mounted suction strainers (e.g., MPN 221217, 25 gpm, 1 1/4 in NPT) provide easy access for maintenance on construction and agricultural equipment.
  • Marine hydraulic systems — LENZ stainless steel suction strainers (e.g., MPN 221203, 50 gpm, 2 in NPT) resist corrosion in saltwater environments.
  • Hydraulic reservoir monitoring — LENZ oil level gauges with thermometer (MPN 221199) allow visual checking of fluid level and temperature in unpressurized tanks.
  • Machine tool hydraulic systems — LENZ suction strainers (e.g., MPN 221215, 10 gpm, 3/4 in NPT) filter fluid in compact power units where space is limited.
  • Hydraulic press maintenance — LENZ replacement strainer elements (100 mesh stainless steel) restore filtration efficiency during scheduled service.

Frequently asked questions

Common questions about LENZ from 3G Electric.

What flow capacities are available for LENZ hydraulic tank suction strainers?

LENZ hydraulic tank suction strainers are offered in flow capacities including 10 gpm, 15 gpm, 25 gpm, 30 gpm, and 50 gpm. These strainers are available with connection sizes ranging from 3/4 in NPT to 2 in NPT, and they feature 100 mesh stainless steel elements. The flow capacity and connection size determine the appropriate model for a given hydraulic system. For example, the 10 gpm strainer with 3/4 in NPT (MPN 221215) is suitable for smaller systems, while the 50 gpm strainer with 2 in NPT (MPN 221203) handles higher flow rates. When selecting a strainer, consider the pump inlet flow and the desired filtration level.

What is the filtration rating of LENZ suction strainers?

LENZ suction strainers use a 100 mesh stainless steel element, which provides filtration down to approximately 149 microns. This mesh size is typical for suction line protection, where the goal is to capture larger particles that could damage the pump. The stainless steel construction offers resistance to corrosion and extends service life. The 100 mesh rating is consistent across the LENZ suction strainer line, including models with different flow capacities and connection sizes. For finer filtration, additional filters may be required in the pressure or return lines.

Are LENZ oil level gauges suitable for pressurized tanks?

LENZ oil level gauges are designed for unpressurized tanks. They are not intended for use in pressurized systems. The gauge features a 1/2"-13 thread, 5 in mounting centers, and a 5.9 in body height, and includes a thermometer for temperature indication. The Buna N seal is rated to a maximum temperature of 212°F. For pressurized applications, a different type of level gauge or sight glass rated for the system pressure would be required. Always verify the pressure rating of the tank and select a gauge accordingly.

What is the difference between internally and externally mounted LENZ suction strainers?

Internally mounted LENZ suction strainers are installed inside the hydraulic tank, typically at the end of the suction line. Externally mounted strainers are installed outside the tank, often on the tank wall or in the suction line. Externally mounted models allow for easier inspection and replacement without draining the tank. LENZ offers both configurations; for example, MPN 221216 is an externally mounted 15 gpm strainer, while MPN 221206 is a 30 gpm strainer that may be internally mounted. The choice depends on system design, maintenance access, and space constraints.

Can 3G Electric provide replacement elements for LENZ filters?

3G Electric supplies LENZ replacement elements and canisters for hydraulic filters. While the current product list highlights suction strainers and oil level gauges, 3G Electric supports the broader LENZ line, including return line filters and replacement parts. For specific replacement element part numbers, contact 3G Electric with the filter model or the original element part number. Providing the filter housing model and the desired micron rating will help ensure the correct replacement is supplied. 3G Electric serves global customers and can assist with cross-referencing and availability.

What materials are used in LENZ suction strainers?

LENZ suction strainers are constructed with stainless steel elements and housings. The 100 mesh filtration element is made of stainless steel, which provides corrosion resistance and durability. The connection threads are typically NPT (National Pipe Taper) and are available in sizes from 3/4 in to 2 in. The stainless steel construction makes these strainers suitable for use with various hydraulic fluids, including petroleum-based and synthetic fluids. The use of stainless steel also allows for cleaning and reuse in some cases, depending on the condition of the element.
