Hyjet INOX Series

The Hyjet Inox series is a premium line of electric water pumps designed for reliable operation, durability, and resistance to corrosion. Made primarily from stainless steel (AISI 304 or AISI 316), these pumps are tailored for clean water applications in both domestic and light industrial settings where hygiene, longevity, and efficiency are key. The Inox series is recognised for its robust construction, quiet operation, and high hydraulic efficiency; making it a preferred choice for users who require dependable water supply solutions.

Design & Construction

One of the standout features of the Hyjet Inox series is its full or partial stainless steel construction.

This includes:

• Pump Body and Impellers: Most models feature a stainless steel pump casing and impellers, which offer excellent resistance to rust, oxidation, and aggressive water conditions.

• Motor Shaft: Made from stainless steel to ensure mechanical strength and resistance to chemical attack, particularly in hard or slightly acidic water environments.

• Mechanical Seal: Typically composed of ceramic and graphite with rubber components (NBR or EPDM), providing a secure, leak-free seal between motor and pump housing.

This design is not only resistant to wear and corrosion but also meets hygiene requirements for potable water and food-grade applications.

Performance and Efficiency

The Hyjet Inox series includes a variety of models, ranging from monoblock centrifugal pumps to multistage horizontal and vertical pumps, each optimized for different pressure and flow demands.

Key performance features include:

• High Hydraulic Efficiency: Thanks to precision-engineered impellers and hydraulic components, these pumps deliver high flow rates and heads with reduced energy consumption.

• Low Noise Operation: Stainless steel components and balanced rotors contribute to smooth, quiet running—ideal for residential installations.

• Wide Operating Range: Models are available in power ratings from 0.37 kW to over 3.0 kW, with flow capacities ranging from a few liters per minute to several hundred, depending on the model and configuration.

Key Features

1. Corrosion Resistance
   The stainless steel construction makes the Inox series highly suitable for use in coastal areas, humid environments, or with slightly aggressive fluids.

2. Compact & Lightweight Design
   The monoblock layout simplifies installation and reduces footprint, making it suitable for confined spaces.

3. Thermal Overload Protection
   Integrated thermal protection (in single-phase models) prevents motor damage due to overheating.

4. Low Maintenance Requirements
   Durable components and high-quality seals reduce the need for frequent servicing, helping to lower lifecycle costs.

5. Versatile Installation
   Suitable for both horizontal and vertical mounting, depending on the model type.

Applications

The Pentax Inox pump series is ideal for a wide variety of applications where clean or slightly contaminated water needs to be moved efficiently:

• Domestic Water Supply: Pressure boosting in homes, apartments, and small buildings.

• Irrigation: Garden irrigation and agricultural sprinkler systems.

• Industrial Use: Water circulation, cooling, or cleaning systems in light industrial setups.

• Water Transfer: From tanks, cisterns, or wells (in shallow applications).

• HVAC Systems: Pumping water in heating or cooling circuits.

• Food & Beverage Industry: Non-corrosive liquid transfer in clean water processes.

The Hyjet Inox Jet pump series stands out for its reliability, performance, and superior resistance to corrosion, making it a versatile solution for domestic and professional water movement tasks. Whether used in homes, farms, commercial buildings, or light industrial processes, these pumps provide a safe, efficient, and low-maintenance option for clean water applications. Backed by the trusted Pentax name, the Inox series is a smart investment in long-term pumping performance.
