Available with 12 VDC and 24 VDC electric motors. Brushless, permanent magnet motors are combined with EMP designed motor control electronics to provide a high efficiency, long life pump. Brushless motors have no contacting parts to wear and reduce life. Features include locked rotor protection, over temperature protection, over current protection, over voltage protection and reverse battery protection.

OP40 offers best in class performance with flow capacity up to 4 gpm and discharge pressure up to 100 psi. Efficient mechanical design along with proprietary software allows sub-zero cold start capability.

OP-40 can be controlled through the following communication protocols: On-Off, J1939 CAN, PWM , EMP-Link (Proprietary LIN). EMP-Link and J1939 CAN versions allow two-way communication to support diagnostics. J1939 CAN communications support J1939 messages defined for Secondary OBD Devices. PWM version provides tach-out feedback (RPM).

Note: J1939 CAN integrated OP-40 available Q1 2017. Interim solution requires use of TMC system controller.

EMP pumps can be run at any speed between the programmed minimum and maximum speed to minimize power consumption and noise. Variable speed can be achieved through a PWM input by varying the duty cycle of the signal. In the absence of a PWM signal the pump will run in a preprogrammed default speed and operate in an on/off manner. EMP’s TMC system controller can also be used to add pressure feedback capability or control for multiple pump systems.

EMP pumps feature positive displacement gerotor type pumping elements allowing for a simpler, quieter, more compact pump design while improving performance and minimizing power loss.

EMP pumps are all 100% flow tested and incorporate internal geometry features to ensure pump will remain wet for improved priming capability.

EMP pumps are sealed and fully submersible for long life operation when exposed to the outside environment and its elements. The pumps are designed and have been validated to withstand submersion and direct spray pressure wash.

Pump head has two sets of suction and discharge ports for ease of installation and plumbing.

EMP pumps can be controlled manually using EMPower Connect™ Service Tool. The software in the pumps can be changed or upgraded in the field using this tool. History data can be downloaded and includes hours of operation, temperature data, voltage data, calibration information and diagnostic fault codes
