Slurry Hose — Suction-Side Transfer of Slurries

Home / Slurry Hose

The recorded duty

The suction family's published application notes put slurries in its working list explicitly: water, light chemicals, slurries, oil and grease transfer and debris-laden flows, across construction, municipal, agricultural and industrial duties. That record is the anchor for the duty. A slurry — solids carried in liquid, from silty water to sand-laden flow — is the duty where a suction hose earns or loses its name, because it combines the intake side's vacuum with an abrasive, settling medium. The family's construction is a smooth flexible PVC inner wall for flow inside a corrugated PVC outer wall. Which wall build a slurry order takes, and the rating at your bore, are specification facts settled in the quotation.

The family's published figures

The suction family's published data — bores 3/4 in to 8 in (suction family range; the rating at your bore is confirmed in the quotation), working pressure 3 to 8 bar (suction family range; the rating at your bore is confirmed in the quotation), burst pressure 9 to 24 bar (suction family range; the rating at your bore is confirmed in the quotation), service temperature -5 °C to +65 °C (suction family range; the figure at your bore is confirmed in the quotation), coils of 10 m to 30 m (suction family range; the lengths offered for your bore are confirmed in the quotation), minimum order 100 m (suction family figure; the minimum for your bore and build is confirmed in the quotation) — stands on the PVC suction hose page. Those figures are the family's ranges across its bores; the rating at your bore is confirmed in the quotation, and for slurry duty that confirmation should be read together with the wall question the family itself raises: it distinguishes thin-wall versions for low-pressure water delivery from thick-wall versions for dust, water and oil transfer. Which wall a slurry order takes is a specification fact — state the slurry and have the wall confirmed, in writing, for your bore.

The facts a slurry enquiry carries

• The solids: what they are — silt, sand, gravel fines, process solids — their particle size and roughly their share of the flow; abrasiveness lives in this line of the enquiry.
• The liquid: water-based or carrying light chemicals or oil — named, with concentration where chemical, because compound suitability is settled per medium.
• Bore against particle: the bore must pass the largest particle without bridging; state particle size and let the bore be answered against it.
• Vacuum and run: the pump's draw, the lift and the run length — slurry settles in slow, long, sagging runs, so route facts matter as much as hose facts.
• Bends and couplings: the route's tight bends and the end connections; abrasive flow cuts at bends first, and couplings are where a slurry line is opened for clearing.

Slurry sits between two neighbouring duties — wet like site dewatering, abrasive like dust transfer — and its specification borrows discipline from both: the set thinking of the one, the wall thinking of the other. Itemise the five facts above, and ask for the quotation to answer for your slurry, at your bore, in the confirmed wall build.

Can the suction hose handle sand-laden water?

Slurries are in the family's recorded duties. State the solids, their size and their share of the flow in the enquiry, and have the wall build and the rating at your bore confirmed in the written quotation.

Thin wall or thick wall for slurry?

The family distinguishes thin-wall versions for low-pressure water delivery from thick-wall versions for heavier transfer duties. Which wall your slurry takes is confirmed per order — state the duty fully and ask for the wall to be named in the quotation.

What about chemical slurries?

Light chemicals are in the family's recorded list, but suitability is compound- and concentration-specific. Name the chemical and its concentration in the enquiry and ask for suitability for that medium to be confirmed in writing.
