What types of water pumps does RETO manufacture?

RETO designs and manufactures brushless DC (BLDC) water pumps for smart toilets, new energy vehicle thermal management, water heater circulation and boosting, all-in-one water purifiers, ice makers, water-heated mattresses, industrial chillers, macerator systems, beer brewing equipment and coffee machines.

Which certifications does RETO hold?

RETO operates under IATF 16949 and ISO 9001 quality management systems and holds TÜV certification. Products comply with CE, RoHS and REACH. The company is recognized as a National High-Tech Enterprise, an SRDI (specialized, refined, distinctive and innovative) enterprise and a high-growth Gazelle enterprise.

Can RETO develop a customized pump for my application?

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.

Custom Hot Water Circulation Pump for Water Heater Supplier, Factories

The CRP060A is a high-efficiency Hot Water Booster Pump engineered for residential hot water recirculation. Utilizing a 36V DC brushless motor rated at 48W, it delivers 20 L/min flow at 11 meters of head pressure — reducing energy consumption by ~60% compared to traditional AC pumps (80–150W). Water heating accounts for 18% of residential energy use (U.S. DOE), and the EPA estimates an average household wastes 11,461 gallons annually waiting for hot water. The CRP060A eliminates this waste with demand-controlled BLDC recirculation, delivering instant hot water at every tap while cutting annual electricity costs to under $1.

Product Description

Product Details

As a dedicated Heat Pump Water Pump, the CRP060A circulates heat-transfer fluid between the evaporator and storage tank, preserving the COP advantage of heat pump water heaters. Its 80°C maximum medium temperature aligns with residential heat pump operating ranges (49°C–60°C tank temperature). DOE Building America field data confirms demand-controlled BLDC recirculation reduces hot water energy use by up to 30% versus constant-pumping systems. For solar thermal or glycol-loop applications, the product line offers compatible models covering radiant floor heating and closed-loop hydronic systems.

Installation & Maintenance

Dedicated Return Line (New Construction): Third pipe from farthest fixture to heater; pump installed on supply side for maximum efficiency.
Thermostatic Bypass Valve (Retrofit): Valve under farthest sink connects hot/cold lines; pump activates when temperature drops below setpoint.
Inlet Screen Inspection (Every 6 Months): Check for debris to prevent flow restriction.
Seal Integrity Check (Annually): Verify all threaded connections remain watertight.
Impeller Inspection (Annually): Flush housing with descaling solution if flow drops >15% below 20 L/min specification.

Specification

Frequently Asked Questions

What voltage does this hot water circulation pump require?

The CRP060A requires 36V DC with 48W power consumption. An external AC-to-DC adapter is necessary for mains-powered installations.

Can the CRP060A handle antifreeze in solar thermal loops?

Yes. The pump supports pure water and antifreeze mixtures within the 0–80°C medium temperature range, compatible with glycol-based solar thermal circuits.

How quiet is the CRP060A during operation?

The CRP060A operates at ≤45 dB at 1 meter—a 10–20 dB reduction compared to conventional AC circulation pumps.

What is the expected lifespan?

The CRP060A is rated for ≥200,000 operating cycles. The brushless DC motor eliminates mechanical brush wear, the primary failure point in traditional designs.

What are the maximum flow rate and head pressure of this unit?

The pump provides a maximum flow rate of 20±1 L/min with a maximum delivery head of 11±1 meters, operating at a rated power of 48W.

What is the waterproof rating and pressure resistance for this model?

The CRP060A features an IPX4 waterproof rating, with a rated constant pressure tolerance of 3.5MPa and continuous pressure rating of 1.5MPa.
