High Pressure Piston Pumps

HOMMAK High-Pressure Piston Pump

A high-pressure piston pump is an industrial pumping solution designed to transfer high-viscosity fluids under high pressure with a precise, loss-free flow rate. Used across a broad range of applications — from tomato paste and margarine to detergent lines and chemical powder production — this pump delivers stable performance even with thick-textured, particle-laden products, thanks to working pressures of up to 600 bar and a low-RPM design. At HOMMAK, we work with you to determine the right pump configuration, supported by engineering tailored to your product and process conditions.

On this page you will find a professional overview of the high-pressure piston pump: its operating principle, technical features, applications, available types, and the points to consider when making your selection.

What Is a High-Pressure Piston Pump?

A high-pressure piston pump is a pump type that moves fluid on the positive-displacement principle, using the suction and discharge cycles of a piston that reciprocates back and forth inside a cylinder. It provides stable flow and precise dosing in high-viscosity products and high-pressure processes where other pump types fall short.

Unlike centrifugal pumps, it does not lose performance as fluid viscosity increases. For this reason it is widely used as a high-pressure piston water pump and as a food-line pump for paste, sauce, cream, filling compounds, polymer blends and fluids containing solid particles.

High-Pressure Piston Pump Features

Key technical features of our pump include:

• Working pressure up to 600 bar: loss-free transfer of high-viscosity products.
• High viscosity compatibility: ideal performance when pumping thick-textured liquids.
• Particle passage up to 50 mm: the ability to convey fluids containing solid particles without crushing them.
• No feed pump required: a single unit handles both suction and discharge, reducing line costs.
• Stainless steel monoblock body: high mechanical and corrosion resistance.
• Gear-reducer drive system: low speed, high torque and long service life.
• Polymeric wear components: product-contact material with high resistance to wear and corrosion.
• Low noise level: an advantage for operator comfort and occupational health and safety compliance.
• Very low RPM: transfer of sensitive products without subjecting them to mechanical stress.
• Easy maintenance: a quick-disassembly modular design with low operating costs.

Engineering note: The performance of a high-pressure piston pump is directly linked to fluid viscosity, particle size, operating temperature and the required flow rate. For the right selection, we recommend contacting the HOMMAK technical team.

Types of High-Pressure Piston Pumps

The types of high-pressure piston pumps vary according to the line they will serve and the product type. The main configurations in the HOMMAK product range include:

• Single-piston (simplex) pumps: for small lines requiring low flow and high pressure.
• Three-piston (triplex) pumps: the most common industrial type, providing low pulsation and stable flow.
• Hygienic (food-grade) pumps: stainless steel versions designed for food lines and compliant with EHEDG and 3-A standards.
• High-viscosity series: a special piston-cylinder geometry developed for products above 100,000 cP, such as paste and margarine.
• Particle-laden product series: a reinforced structure for fluids containing solid particles up to 50 mm.

To determine which type suits your line, the product viscosity, operating temperature, flow rate and required pressure values need to be assessed.

What to Consider When Choosing a High-Pressure Piston Pump

The right pump choice directly determines line efficiency and total cost of ownership. The parameters you should check during the selection process are:

1. Fluid viscosity (cP): make sure the pump is compatible with the fluid’s viscosity range.
2. Working pressure (bar): the maximum pressure demanded by the line should stay below the pump’s nominal rating.
3. Flow rate (m³/h or L/min): capacity should be selected to match the line’s requirement.
4. Particle size: the largest solid particle in the fluid must be smaller than the pump’s passage diameter.
5. Temperature: both product and ambient temperature are decisive factors in material and sealing selection.
6. Product sensitivity: low-RPM models should be preferred for products sensitive to high shear stress.
7. Hygiene requirements: CIP/SIP-compatible models should be selected for food and pharmaceutical lines.

Frequently Asked Questions (FAQ)

Up to how many bar does a high-pressure piston pump operate?

The HOMMAK high-pressure piston pump is designed to provide a working pressure of up to 600 bar. This makes stable, efficient transfer possible for thick-textured products such as paste, margarine, sauce and high-viscosity chemicals. The working pressure can be customized according to the line’s demand and the selected model.

Which products can a high-pressure piston pump pump?

The pump can safely convey high-viscosity fluids, products containing particles up to 50 mm, and delicate-textured food blends. Tomato paste, margarine, sauce, concentrated milk powder, protein suspensions, detergents and viscous chemical mixtures are among the main use cases.

What is the difference between a high-pressure piston pump and a high-pressure piston water pump?

A high-pressure piston water pump is generally designed for low-viscosity fluids with few particles. An industrial high-pressure piston pump, on the other hand, runs on a special piston-cylinder geometry, low RPM and gear-reducer drive for high-viscosity, particle-laden and sensitive products.

How are high-pressure piston pump prices determined?

Price is determined by the pump’s working pressure, capacity, body material (stainless steel grade), sealing selection, hygiene standards (food/pharmaceutical grade) and special product requirements. Rather than a standard list price, the correct approach is to offer a custom quote based on your process data.

Is maintenance of a high-pressure piston pump difficult?

No. HOMMAK pumps can be quickly disassembled and cleaned thanks to their modular design. Because the wear components are produced from high-resistance polymeric material, spare-part replacement intervals are long. With a regular maintenance schedule and the use of original spare parts, pump service life is extended significantly.

In which industries are high-pressure piston pumps used?

The primary application areas are food processing (tomato paste, sauce, margarine, milk powder, protein powder), chemicals (pre-stage mixtures for chemical powders), detergents (liquid detergents and concentrate formulas) and cosmetics. They are preferred on every line where viscosity and pressure are both high at the same time.
