High Pressure Piston Pumps

Cargando...

Efficient transfer of high-viscosity fluids.

High-pressure piston pumps HM Series designed for high-efficiency positive pumping of viscous fluids up to 600 bar without cavitation. They replace inefficient multiple pumping systems and act as the core feed for drying towers (Spray Dryers) or ultrafiltration systems. The positive suction capacity handles dense products without prior centrifugal feed pumps, simplifying process lines and reducing global electricity consumption. Unlike homogenizers, these pumps are designed to maintain pressure and transport fluid or feed other equipment (such as atomization nozzles), without dissipating energy in particle rupture.

This unit replaces inefficient multiple-pump systems. It acts as the feed heart for spray drying towers or ultrafiltration systems. Its positive suction capability allows handling dense products without prior centrifugal feed pumps, simplifying the process line and reducing overall electricity consumption.

Main Advantages

Viscosity Management: Ideal for concentrates and pastes that would cause cavitation or blockage in standard pumps.
Line Simplification: Eliminates the need for booster or feed pumps in most applications.
Abrasion Resistance: Selectable valve and seat materials (Stellite, Tungsten Carbide) to resist abrasive solids.
Flow Stability: Constant flow rate independent of back pressure, crucial for uniform atomization in spray dryers.
Capacity Range: From 500 L/h to 25,000 L/h depending on model and required pressure.
Processable Products: Tomato paste, fruit concentrates, powder detergent mixtures, condensed milk, vegetable purees.
