6 - Pump Installation

The 1900e series pump is protected with a double box during shipping.  It 

can be lifted from the box by the heat sink.

Warning:

 Pump may be heavy. Provide yourself help if 

needed. 

Warning:

 The majority of mechanical seal failures are due 

to  poor  media  (fluid)  quality  in  the  system.  To  maximize 

seal life, media quality must  be maintained in the system, 

and TDS (Total Dissoled Solids)/TSS (Total Suspended 

Solids) should not exceed 500ppm with standard carbon/

Silicon-Carbide seals. The use of inhibitor based glycols is acceptable, 

but additional inhibitors should not be added. Always follow the  glycol 

manufacturer's  specification  for  system  preparation  and  water  quality. 

Treatment with silicates should not be used. Failure to maintain media 

quality will void the standard Taco warranty.

AVERTISSEMENT: 

La plupart des défaillances des garnitures mé-

caniques sont dues à une mauvaise qualité de caloporteur. Pour pro-

longer la durée des joints, on doit maintenir la qualité du fluide dans le 

système et les solides dissouts totaux (SDT)/matières en suspension to-

tales (MES) ne doivent pas dépasser 500 ppm avec des joints standard 

en carbone/carbure de silicium. L'utilisation de glycols/inhibiteurs com-

binés est acceptable, mais on ne doit y ajouter aucun inhibiteur supplé-

mentaire. Suivez toujours les spécifications du fabricant du glycol pour la 

préparation du système et la qualité du fluide. On ne doit pas utiliser de 

traitement aux silicates. Ne pas maintenir la qualité du fluide annulera la 

garantie standard de Taco.

AVERTISSEMENT:

 La pompe est lourde. Veillez à de-

mander de l’aide si nécessaire.

It is recommended that the1900e series 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.

The 1900e series model pumps can be installed with the motor shaft in the 

horizontal position or the vertical position with the control module facing up 

(see Figure 1).  The cover can be rotated independent of the pump to adjust 

orientation of the User Interface – the cable glands should never be pointed 

upward to mitigate water ingress.  The desired conduit box orientation can 

be achieved by rotating the motor housing on the pump casing.

Caution:

 When reassembling, care should be taken to avoid damaging the 

o-ring and insuring a good seal.

Attention!

 Operation outside recommended conditions may shorten pump 

lifetime and void the warranty.

7 - Motor Rotation Procedure

Caution:

 If system is filled and pressurized, shut off valve before and after 

the 1900e series pump. Allow to cool if system fluid is hot.

Notice! 

It is recommended to always change the orientation of the motor 

before installing pump in piping.

5 - Pumped Fluids

In hot and chilled hydronic systems, use water or water/glycol mixtures only. 

Water/glycol mixtures must be HVAC-system compatible and should have 

no  more  than  50%  concentration  of  glycol. The  fluid  shall  not  consist  of 

aggressive or explosive additives, mixtures of mineral oils or solid or fibrous 

particles. The pump should not be used for pumping flammable, explosive 

fluids, or in an explosive environment.

Desired pump orientation can be achieved by rotating the pump casing. 

The pump is mounted to the volute with four screws. By removing those 

the head can be turned. See detailed Motor Rotation Procedure 7 below.
