Dolphin Strainers

Dolphin Floating Suction Strainers draw from just below the surface, avoiding sand, mud and floating matter. They do not get buried when grounded in shallow water and are made entirely of tough, corrosion resistant plastics and stainless steel.


Key Points

- Reduce wear of pumps
- Prevent pump damage
- Prevent stoppages
- Lessen cavitation risk
- Save their cost many times over
- Always float upright
- Will not lose buoyancy
- Tough, shock-proof
- Corrosion proof


Used for dewatering mines, quarries, excavations and sumps. For water supplies from rivers, lakes, ponds and fire appliances. They are also used for oil storage and other installations required to draw from near the surface.


The strainer holes are 3/16” diameter, the total area of the holes being between 3 and 4 times the cross-sectional area of the hose. The 6” size has a perforated body which along with the tube is constructed entirely of 18/8 stainless steel. Other sizes have replaceable strainer screens made from Darvic black P.V.C. Standard strainers are suitable for operating temperatures up to 194ºF (90ºC), but for temperatures above 150ºF (65ºC) stainless steel strainer plates are available as an optional extra.
