them from any and all responsibility and shall also cause the warranty to become null and void. 

 
 

PUMP DESCRIPTION 

 

Hawk high pressure piston pumps are volumetric pumps. 
As may be inferred from the header in this document, 4 pump series are described below, which are slightly different from one another. 

 

PUMPS NMT-EBCW 

This series consists of a brass head called 

ECOBRASS, 

plated with a chrome layer.

 

The piston seals are made of rubber fabric, while the other seals are made of NBR. 
The admitted work fluids are summarized in the table below 
 

PUMPS NMT-EBCH, XLTI-EBCH 

This pump consists of a brass head called ECOBRASS 
the piston seals are made of TEFLON (PTFE), while the other seals are made of FKM (Viton). 
The admitted work fluids are summarized in the table below. 

 

PUMP XLTI-ESA 

This pump consists of an AISI 316 stainless steel head. 
The piston seals are made of TEFLON (PTFE), while the other seals are made of HNBR. 
The admitted work fluids are summarized in the table below.
