5. PUMP DESCRIPTION
The high efficiency, electronically commutated 00e VR15 - 30 model pumps consist of two main parts, the centrifugal
pump and the electronic control. The hydraulic part is hermetically sealed from the motor assembly and has no mechanical
seals. 00e pumps are powered by an electronically commutated permanent magnet motor (ECM) which does not consume
energy to magnetize the rotor, providing superior energy efficiency. The ECM is controlled by an on-board frequency
converter. The converter estimates current flow and head from the motor load, information essential for self-sensing
system reactive operation.
6. USE
All Taco 00e VR pumps are intended for circulation of solid-free fluid in pressurized, hot and chilled hydronic systems.
The self-sensing ECM pump constantly calculates pressure and flow, and adapts its speed to the appropriate flow.
Stainless steel models are intended for potable drinking water applications and can be used for HVAC systems as well.
7. PUMPED FLUIDS:
Use water and water/glycol mixtures only. Water/glycol mixtures must be HVAC-system compatible and should have
no more than 50% concentration of glycol. Excessive glycol concentrations may lead to reduced performance. The
fluid shall not consist of aggressive or explosive additives and mixtures of mineral oils and solid or fibrous particles.
The pump should not be used for pumping flammable, explosive fluids, and in an explosive environment. To reduce
potential abrasive damage a magnetic iron removal device is recommended to remove excessive iron-oxide from the
system fluid.
8. PUMP INSTALLATION:
The 00e® pump is protected with a double box packaging during shipping. It can be lifted from the box with
internal handles or by lifting it by the heat sink. The included insulation shell reduces thermal energy loss to the
surrounding environment and protects the pump from shipping damage.
Pumps are designed to be installed using standard ANSI class 125 flanges. It is recommended that the 00e pumps be installed
with at least 5 to 10 pipe diameters of straight pipe on the inlet and outlet of the pump. Use all nuts and bolts to attach
companion flanges to the pump flanges.
All VR model pumps should be installed with the motor shaft axis in a horizontal position (see Figure 1). Failure to do so
may result in excessive noise and vibration, premature bearing failure and may void warranty.
Desired pump orientation can be achieved by rotating the pump casing. The pump is mounted to the volute with four
screws. By unscrewing those the head can be turned. See detailed Motor Rotation Procedure 8.1 below.
Caution: When reassembling, care should be taken to avoid damaging the o-ring and insuring a tight seal
CAUTION: Pump may be heavy. Provide yourself help if needed.
ATTENTION: La pompe est lourde. Veillez à deman-der de l’aide si nécessaire.
ATTENTION!! Installing pumps in UNAUTHORIZED positions will result in voiding the warranty.
For replacement O-Rings please consult Repair Parts List.
