Water Circulation Pumps & Circulators

00e® Series VR ECM High-Efficiency Circulators The 00e® series — These are browser accessible, high-efficiency, wet rotor, variable speed, sensorless commercial pumps for chilled and hot water applications. Available in four sizes (VR 15-3, 20-3, 25-3 and 30-3), the sensorless 00e VR line provides differential head pressures up to 42 ft. and flows up to 360 GPM. The ECM motor provides up to 85% electrical energy savings compared with conventional pumps and its multiple operating modes fit most applications. • Simple user interface to enable setting changes on the face of the pump, eliminating the need for laptop setup • Real-time performance readouts for flow, power consumption, speed and head values • Self Sensing Dynamic Auto (factory default), Proportional & Constant Pressure plus Manual Variable Speed modes provide for extremely extensive application flexibility • On board 0-10Vdc two way control adjusts speed or head to meet system demands from external control inputs • ModBus control and performance feedback for advanced Building Management / Building Automation Systems

Web connections are a snap.

A convergence of efficiency, simplicity & technology. Efficiency as the basis of design The ECM based design combines a brushless Electronically Commutated Motor with a strong permanent magnet rotor. An ECM motor does not waste any energy in order to magnetize the rotor and the position of the magnetic poles of the rotor and stator generate continuous thrust in the rotating direction of the rotor. The integral electronics Continuous Commutation

The position of the magnetic poles of the rotor maintains ultimate motor EFF over the speed and load range of the unit.

Up to 85% Electrical Savings Connecting with Ethernent crossover cable

Connecting with LAN

precisely drive the rotor as fast as the rotating flux, significantly reducing motor efficiency losses while greatly increasing starting torque. Full variable speed control matches system requirements The electronics continually adapt the speed to match the requirements of the system. Because the electrical motor is being driven by an on-board frequency converter the electric current is rectified and converted into the appropriate phase angle to maximize energy efficiency, even when operating at hydraulic partial load conditions. The superior motor efficiency, optimized speed control, and intelligent sensorless variable speed pump control delivers dramatic cost savings over the life of the system.

Flexibility to fit the job The hydraulic characteristics of the pump can be set at will. Pump regulation can be done by pressure, speed, electrical power or a combination of these, so it can be adapted to different hydraulic system requirements without the need for external regulators or sensors. Ready-to-go out of the box, this pump will automatically adjust its speed based on internally sensed variable differential pressure control, providing optimal energy savings across the industry’s largest operating range. Additional modes of control can be selected to provide constant pressure control, proportional pressure control, constant curve duty (uncontrolled pump), multiple speed, RPM regulation or power limitation control. These pumps can be operated as single, parallel or series variable speed pumps. The onboard electronics allows the user to choose to run two pumps in parallel, standby or alternating modes. The built-in normally open, or normally closed relay contacts can be used to activate or deactivate a primary or secondary pump contact, provide external operation or overload feedback or switch another piece of equipment. In addition, this pump comes standard with 2 external digital inputs and 1 external digital output to be available for additional mechanical room control and pump monitoring.

Taco; the new generation of wet rotor pumps. Heating, air conditioning or chilled water systems These pumps are built to exacting specifications meeting the widest range of closed loop hydronic heating and cooling applications. They are suitable for use with fluids at temperatures from 14°-230°F (-10° - 110°C), feature 175psi working pressure and have a stainless steel impeller and shaft. Continuous duty rated with a built-in soft start-up circuit the VR15-3 & VR20-3 can accept 110-240 volt and the VR25-3 and VR30-3 operate on 230-240 volt supply power.

Adjustments for Proportional Pressure, Constant Pressure and Fixed Speed can now be made directly on the pump. The in-line design and standard ANSI class 125 flanges make for a technician friendly installation. The pump and motor form an integral unit without a mechanical seal. The bearings are lubricated by the pumped fluid, ensuring years of quiet, maintenance free operation.

To protect your investment in the pump it provides dry run, overcurrent, line surge and current limit protection, thermal monitoring, heat sink status and over temperature protection. Given all the advantages stated above, the total cost of ownership of the pump is by far the lowest for its performance range.
