Pedrollo JCRM-1A -EP1 Series


Installation and Use
Pedrollo JCRM1A-EP1 Pump – Reliable, Quiet, and Energy-Efficient Water Management
The Pedrollo JCRM1A-EP1 is a standout model in the trusted Pedrollo pumps range. It offers excellent engineering, sturdy construction, and efficient operation.
Although technically a self-priming jet pump, its performance rivals many energy-efficient stainless steel multistage pumps in home and commercial settings.
This model pairs the power of the Pedrollo pump JCRM 1A with an EP1 electronic controller. Together, they create a modern, automated solution for household water systems.
It works well for pressure boosting, garden irrigation, tank refilling, and any water transfer where control and consistency matter.
Design and Construction: Durable Stainless Steel Performance
A key strength of the JCRM1A-EP1 is its durable construction. Like all high-quality Pedrollo pumps, it uses AISI 304 stainless steel.
The body, impeller, and outer shell resist corrosion and wear. This material also keeps water safe for drinking use.
The shaft is made from AISI 431 stainless steel, adding strength and resisting mechanical damage.
Meanwhile, the ejector and diffuser use Noryl™, a tough thermoplastic that handles heat, water, and chemicals with ease.
These materials ensure reliability in harsh environments or during frequent stop-start cycles.
Performance and Operation: Quiet and Efficient
The pump runs on a 0.55 kW (0.75 HP) single-phase motor powered at 240V.
It provides up to 60 L/min (3.6 m³/h) flow and reaches heads of 48 meters.
Despite the power, the pump remains quiet, making it ideal for indoor use or areas sensitive to noise.
Its self-priming jet system allows suction up to 9 meters, even with air in the pipe.
This makes it perfect for rainwater tanks, shallow wells, or cisterns where water flow is inconsistent.
The motor features thermal protection and supports continuous duty (Service S1), reducing wear and avoiding overheating.
Smart Control with the EP1 Unit
The EASYPRESS EP1 controller adds smart functionality. It starts the pump when pressure drops and stops it when demand ends.
The controller includes built-in dry-run protection, which prevents operation when no water is present.
This feature guards against one of the most common pump failures.
A microprocessor tracks both flow and pressure to ensure safe and efficient performance.
This technology eliminates the need for manual operation. It also reduces wear, cuts energy use, and extends pump life.
Practical Applications
The Pedrollo JCRM1A-EP1 suits many tasks that involve clean water movement or pressure.
Typical uses include:
Water supply from tanks or shallow wells
Boosting pressure for showers, taps, and appliances
Irrigation for lawns, gardens, and small farms
Filling tanks or transferring water across distances
Use in wash systems or pressure cleaning setups
Thanks to its self-priming feature, it performs well even when some air enters the line.
This makes it ideal for rainwater harvesting systems or homes with irregular water levels.
Energy-Efficient and Eco-Friendly
Though not multistage, the JCRM1A-EP1 matches many stainless steel multistage pumps for energy efficiency.
Its smart controller avoids needless motor cycling, reducing power use and mechanical strain.
The pump only runs when needed. This cuts energy waste and lowers your running costs.
As a result, it works well for eco-conscious homes and off-grid systems that demand efficiency and reliability.
