metaDescription: How to select and size a fluid transfer pump for your medium, flow and head — and the pump types that suit gentle, viscous or general transfer.Content blocks
content.introA fluid transfer pump moves a liquid from one place to another — tank to tank, process to filler, delivery to storage. The right pump depends on the liquid: a thin, clean liquid like water suits a different pump from a thick, particle-laden or delicate one. Channel Pumps sizes and supplies the pump to your duty: medium, flow and head.

content.the_dutyFluid transfer means moving a set volume of liquid at a set rate, safely and without damaging the liquid or the pump. What makes it demanding is the liquid, not the act of moving it. Viscosity — how thick the liquid is — changes how easily it flows. Temperature, solids content and abrasiveness change what the pump's wetted parts must survive. Some media are shear-sensitive and degrade if handled roughly. Others are hazardous or hygienic, which constrains the materials and the design. A pump sized for clean water will struggle, or fail, on a viscous or solids-laden fluid. So the first question is always: what are you moving?
content.selectionSelect the pump around the medium first, then the duty point. For thin, clean liquids at higher flows, a centrifugal pump — which uses a spinning impeller to add energy to the liquid — is efficient and cost-effective. For thick, viscous, delicate or metered flows, a positive displacement pump — which traps a fixed volume of fluid and moves it per revolution — holds flow steady whatever the pressure. Fix the duty point next: the flow rate you need, and the head, the pressure the pump works against, expressed as a height of liquid. Then match materials to the medium — the seals, elastomers and metallurgy that resist your liquid's chemistry, temperature and any abrasives. Give Channel Pumps these four — medium, flow, head, materials — and we specify the pump.
content.key_featuresLook for a pump matched to your medium and duty, not a general-purpose default. Check the wetted materials are rated for your liquid's chemistry and temperature. Check the flow and head meet your duty point with margin. Check the seal type suits the medium — a mechanical seal, or a seal-less design for aggressive or hazardous fluids. Check for self-priming ability if the pump sits above the liquid, and for solids-handling clearance if the fluid carries particles. For metered or shear-sensitive transfer, favour positive displacement. For high, clean flows, favour centrifugal.

content.faq[]4 itemscontent.faq[0]content.faq[0].questionWhat is a fluid transfer pump?
content.faq[0].answerA fluid transfer pump moves a liquid from one point to another — tank to tank, or process to filler. The right type depends on the liquid: thin and clean, or thick, delicate or solids-laden.
content.faq[1]content.faq[1].questionCentrifugal or positive displacement for transfer?
content.faq[1].answerUse a centrifugal pump for thin, clean liquids at higher flows. Use a positive displacement pump for viscous, shear-sensitive or metered transfer, where it holds flow steady against changing pressure.
content.faq[2]content.faq[2].questionWhat does Channel Pumps need to size a transfer pump?
content.faq[2].answerFour things: what you're moving (the medium, its viscosity, temperature and solids), your flow rate, the head the pump works against, and any hygiene or hazardous-area requirement.
content.faq[3]content.faq[3].questionCan one pump handle different liquids?
content.faq[3].answerSometimes. A positive displacement pump handles a range of viscosities on one platform, but the wetted materials and seals still have to suit every medium. Tell us the full range.
