Yes. RETO's R&D team includes more than 10 senior engineers, each with over 10 years of industry experience in motor design, control systems, hydraulics and structural design. Custom designs are validated through laboratory and real-application testing before mass production.

What information is needed for an accurate custom pump proposal?

Please share the pumped medium and its temperature range, required flow rate and head, supply voltage, control method such as PWM speed control or FG feedback, duty cycle and expected service life, installation space and port dimensions, noise target, and the certifications required for your target market.

What is RETO's production capacity?

With automated and semi-automated production lines, RETO's annual output exceeds 2 million pump units. Key processes undergo 100% inspection to keep quality consistent across large OEM orders.

Why choose a brushless DC pump instead of a brushed DC pump?

A brushless DC pump has no carbon brushes to wear out, so it typically offers a longer service life, lower operating noise and less electromagnetic interference. Electronic commutation also allows precise speed control, which makes BLDC pumps well suited to continuous-duty appliances and vehicle cooling loops.

Product Description

Product Details

Home Hot Water Circulation Pump

As a Home Hot Water Circulation Pump, the CRP035A helps reduce the wait time for hot water in residential settings. By circulating cooled water in the pipes back to the heater, it ensures hot water is readily available at the tap.

Quiet Operation: Noise level of ≤40dB @ 1m ensures quiet running, minimizing disturbance in living spaces.
Reliable Safety: Built-in protection mechanisms prevent damage from dry running or overheating, ensuring safe operation in home plumbing systems.

Solar Hot Water Circulation Pump

When used as a Solar Hot Water Circulation Pump, the CRP035A's 24V DC rating allows for direct compatibility with solar power systems. This eliminates the need for complex AC conversions, improving overall system efficiency. Its compact size and lightweight design (216g) make it easy to install in tight spaces often found in solar thermal setups.

Hot Water Heater Booster Pump

For applications requiring consistent flow, this unit serves effectively as a Hot Water Heater Booster Pump.

Performance: Delivers a maximum flow of 18 L/min (approx. 1080 L/H) and a maximum head of 8m, providing sufficient pressure to overcome resistance in typical household piping and heat exchangers.
Compact Installation: Small form factor allows for inline installation directly on the water heater's inlet or outlet without requiring significant plumbing modifications.

Technical Specification

The CRP035A is designed to integrate seamlessly with standard water heater systems. Its technical specifications are optimized for efficiency and durability:

Efficient Power Consumption: With a rated power of 24W and a rated current of 1A, it offers high efficiency without overloading the water heater's control board.
High-Temperature Resistance: Rated for a medium temperature of up to 98℃, making it suitable for hot water circulation where temperatures approach boiling point.
Robust Protection: Featuring an IP68 waterproof rating, the fully sealed housing prevents moisture ingress, ensuring safety even in humid installation environments like under-sink cabinets or outdoor units.

Frequently Asked Questions

Q1: Can this pump handle near-boiling water?

Yes, the CRP035A is rated for liquid medium temperatures up to 98℃ (-40~98℃ range), making it suitable for most hot water circulation applications. For continuous operation at extreme peak temperatures, consulting our engineering support helps ensure optimal lifetime performance.

Q2: Is this pump suitable for large commercial buildings?

This model is designed primarily for residential and light commercial use, such as single-family homes and small apartments. For large-scale industrial or commercial setups requiring higher flow capacities (>20 L/min) or heavier head pressures, our specialized high-capacity commercial pump series is recommended.

Q3: What is the expected lifespan of this pump?

The unit features a brushless magnetic drive configuration rated for ≥2000 hours of continuous service. By eliminating direct mechanical friction surfaces found in traditional brush motors, it delivers sustained reliability across typical heating and circulation duty cycles.

Q4: Can the CRP035A pump run directly on solar power systems?

Yes, the pump operates on a 24V DC input, allowing direct integration with solar thermal systems, DC batteries, and solar controllers without requiring additional DC-to-AC power inverters, maximizing overall energy conversion efficiency.

Q5: What protection rating does this pump feature for wet environments?

The pump features a fully sealed IP68 waterproof enclosure combined with class H (180℃) insulation. This level of ingress protection makes it safe for high-moisture spaces, outdoor installations, and damp under-sink plumbing cabinets.

Q6: What liquids and working pressures can this pump handle?

The CRP035A is compatible with pure water and antifreeze solutions. It supports a constant pressure of up to 1.5 MPa and a continuous working pressure of 0.5 MPa, suitable for residential closed-loop and open-loop plumbing networks.
