One-Minute Overview

In-line basket strainer with a removable stainless basket that collects debris from water, oil and process media.
Sizes 2 to 24 inch, pressure classes 150LB to 600LB to ASME B16.34.
Large dirt holding area means fewer stops for cleaning on continuous lines.
The basket lifts straight out once the cover is off, so servicing is quick.

A basket type strainer puts a cylindrical screen in the flow path and drops debris into a sump below it. The straight-through body keeps pressure drop low, and the screen area is much larger than a Y strainer of the same line size, which is why basket strainers sit on pump suction, cooling water and other lines that carry a steady load of solids. The cover lifts off without disturbing the pipe, and the basket comes out as one piece for cleaning.

Feature: Removable stainless basket with large dirt holding area

Size the strainer for the pump, not just the pipe: the open area of the basket should keep velocity through the screen low enough that pressure drop stays modest at design flow. Install on a horizontal run with the flange bolts accessible, and leave cover clearance for lifting the basket out. A drain connection under the sump makes blow-down easy; strainers on pump suction should be sized generously to avoid cavitation.

Cleaning is a routine job: isolate the strainer, vent it, take off the cover, lift the basket and wash it back to front so debris leaves the way it came. Watch the differential pressure across the body; a steady rise means the basket is loading up. Basket mesh, body material and flange class are confirmed per inquiry, and a detailed specification sheet is available on request.

FAQ

Q1. How large should the basket open area be relative to the line?

The rule of thumb is three to four times the pipe cross-section, which keeps velocity through the screen low and pressure drop modest. Undersized baskets blind quickly and force frequent stops. When the solids load is heavy, prefer a larger body with a deeper basket over a fine mesh in a small shell.

Q2. Can I hang this strainer on a vertical line, or does it have to sit flat?

Horizontal is the default and the easiest to service. Vertical installation works if flow travels downward, so the basket fills and drains as designed. Upward flow can float debris back into the line, which defeats the whole point. Whatever the orientation, leave cover clearance so the basket lifts straight out.

Q3. The differential pressure gauge will not sit still - what is it complaining about?

It is complaining about the basket, most likely. A steady climb in differential pressure means solids are building up on the screen. Isolate, vent, lift the cover and wash the basket back to front so debris leaves the way it came. If the gauge climbs again within days, look upstream for the source.

Q4. How long will production take?

Standard sizes are typically ready within 30 days, and in-stock items ship immediately. Larger or custom orders get a confirmed date per order, because the schedule depends on quantity, material, the bolt pattern you specify, and how busy production is at the moment you order.
