What Pumps for Paste Products suppliers provide

Suppliers in this category cover pump types designed specifically for viscous and shear-sensitive media that standard centrifugal pumps cannot handle reliably, including progressive cavity, lobe, and peristaltic pumps. These designs move product gently, at controlled shear, to avoid damaging particulates or altering the product’s texture, which matters for foods such as sauces, purées, and creams as well as cosmetic and chemical pastes. Core competence lies in matching rotor or hose material, clearances, and cleaning design to the product’s viscosity and hygiene requirements. Many suppliers offer clean-in-place or sanitary designs for food and pharmaceutical use, along with sizing support and spare parts. Unlike pumps for liquid products, which handle free-flowing fluids, this group is built for media that would clog, separate, or shear-damage in a conventional pump. In the pre-selection phase, compare which viscosity ranges and hygiene standards each supplier’s designs cover.

Relevant standards

For food and pharmaceutical applications, pumps for paste products are commonly built to hygienic design principles published by EHEDG, with wetted parts complying with EU Regulation 1935/2004 on food-contact materials. Supplier quality management is typically certified to ISO 9001.

Frequently asked questions

Why can’t standard centrifugal pumps handle paste products?
Centrifugal pumps rely on high-speed impellers that can shear-damage viscous or particulate-laden products and lose efficiency as viscosity rises, so paste applications typically require progressive cavity, lobe, or peristaltic designs instead.
