Product catalog summary
Overview: This document provides technical specifications and ordering information for tank immersed suction strainers, specifically the STR series, which are designed for flow rates up to 900 l/min. The strainers are compatible with various types of oils and synthetic fluids as per ISO standards.
Specifications:
  • Compatibility: Conforms to ISO 2943, suitable for mineral oils (HH-HM-HR-HV-HG) and synthetic fluids (HS-HFDR-HFDS-HFDU). For other fluids, consult the Engineering - Sales Department.
  • Materials: Connection, cap, and valve are made of nylon, while support tubes are galvanized steel.
  • Filtration: Available in three mesh sizes: M60 (60 micron), M90 (90 micron), and M250 (250 micron).
  • Bypass Valves: Opening pressure is 30 kPa ± 10%.
  • Temperature Range: Operates from -25°C to +110°C.
  • Flow Direction: Oil flows from exterior to interior.
Technical Data:
  • Pressure Drop: The pressure drop (Δp) curves are based on mineral oil with a reference viscosity of 30 mm²/s (cSt) according to ISO 3968.
Dimensions and Weight: The document provides detailed dimensions and weights for various sizes and configurations of the STR strainers, including versions with and without bypass valves.
Ordering Information:
  • Part numbers and sizes are specified, with options for valve type (with or without bypass), connection type (BSP or NPT thread), filter element type (M60, M90, M250), and additional options (e.g., MP Filtri standard).
