DESCRIPTION:

The 0034ePlus is a high performance, variable speed, high-efficiency, wet-rotor 

circulator with an ECM, permanent magnet motor and an advanced digital LED 

display controller for easy programming and diagnostic feedback. With 5 operating 

modes and simple keypad programming, its variable speed performance curves are 

equivalent to the Taco 009, 0010, 0011, 0012, 0012 3-Speed, 0013, 0013 3-Speed & 

0014. Ideal for large residential and light commercial hydronic heating, chilled water 

cooling and domestic hot water systems. The 0034ePlus reduces power consumption 

by up to 85% compared to equivalent AC permanent split capacitor circulators.

APPLICATION:

•  Maximum operating pressure: 150 psi (10.3 bar)

•   Minimum NPSHR: 18 psi at 203˚F (95˚C)

•   Maximum fluid temperature: 230°F (110˚C)

•   Minimum fluid temperature: 14°F (-10˚C)

•   Electrical specifications:

   

Voltage: 115/208/230V, 50/60 Hz, single phase

   

Maximum operating power: 170W

   

Maximum amp rating: 1.48 (115V) / .70 (230V)

•   Equipped with a cast iron or stainless steel casing

•   SS Model suitable for open loop potable water systems

•   Taco circulator pumps are for indoor use only – employer uniquement a l’interieur

•   Acceptable for use with water or maximum of 50% water/glycol solution

FEATURES:

•  Simple keypad programming

•  Digital LED screen display (Watts, GPM, Head, RPM and diagnostic error codes)

•  Five operating modes to match any system requirements - activeADAPT,  

 

 

 

 

 

  Constant Pressure, Proportional Pressure, Variable Fixed Speed or 0-10V DC input

•   Replaces all single speed and 3-speed circulators in its class

•   ECM performance equivalent to Taco’s 009, 0010, 0011, 0012, 0013 & 0014 circulators

•   Multi-color LED display showing power on, mode setting and error code diagnostics

•   Use with a Taco ZVC Zone Valve Control or SR Switching Relay for ON/OFF operation

•   Nut-capture feature on flanges for easier fit up

•   Dual electrical knockouts and removable quick-connect terminal strip for easy wiring

•   Double insulated

•   Whisper quiet operation

•  

BIO Barrier®

 protects the pump from system contaminants

•  

SureStart®

 automatic unblocking and air purging mode

•   Rotatable control cover to allow any pump body orientation 

INSTALLATION:

WARNING: Do not use in swimming pool or spa areas. Pump has not been investigated for these applications.

AVERTISSEMENT : Ne pas utiliser dans une piscine ou un spa. La pompe n’a pas été étudiée pour ces applications.
CAUTION: The addition of petroleum based fluids or certain chemical additives to systems using TACO equipment

voids the warranty. Consult factory for fluid compatibility.
ATTENTION : L’ajout de liquides à base de pétrole ou de certains additifs chimiques à des systèmes utilisant un

équipement TACO annule la garantie. Consultez le fabricant pour connaître la compatibilité de liquides.
CAUTION: Installations at elevations over 5000 feet must have higher fill pressure of 20 psi minimum to prevent

pump cavitation and flashing. Premature failure may result. Adjust expansion tank pressure to equal fill pressure. 

A larger size expansion tank may be required.
ATTENTION : Des installations à des altitudes de plus de 1600 mètres doivent présenter une pression de remplissage plus élevée de 20 psi 

au minimum afin d’éviter toute cavitation ou flashing de la pompe. Une défaillance prématurée peut en résulter. Réglez la pression 

du réservoir d’expansion de façon qu’elle soit égale à la pression de remplissage. Un réservoir d’expansion d’une taille supérieure 

peut être nécessaire.
