Product catalog summary

Overview: This document provides technical specifications and ordering information for the STR series of in-tank suction strainers, designed for hydraulic systems with flow rates up to 250 gallons per minute (gpm). The strainers are available in two styles, S and B, with or without bypass valves.

Compatibility: The strainers are compatible with mineral oils (types HH, HM, HR, HV, HG) and synthetic fluids (types HS, HFDR, HFDS, HFDU) as per ISO 6743/4. For aqueous emulsions (types HFAE, HFAS) and other fluids, consultation with the Engineering - Sales Department is recommended.

Materials: The strainers are constructed with nylon connections, galvanized steel support tubes, nylon caps, and nylon-steel valves.

Filtration: Available filtration levels include 60 micron (M60), 90 micron (M90), and 250 micron (M250).

Bypass Valves: The bypass valves have an opening pressure of 4.35 psi ± 10%.

Temperature Range: The operational temperature range is from -13°F to +230°F.

Flow Direction: Oil flows from the exterior to the interior of the filter.

Pressure Drop: Pressure drop curves are provided based on a reference viscosity of 30 mm²/s (cSt) (150 SUS) according to ISO 3968.

Dimensions and Sizes: The document lists various sizes and dimensions for the strainers, including connection types (BSP and NPT threads) and weights.

Ordering Information: The ordering code includes size, valve type, connection type, filter element, and options. MP Filtri reserves the right to modify the information as needed.
