Emtec: Advanced Technology for Long Service Life Emtec pumps are specifically designed to withstand the harsh environment of high pressure machine tool coolant service. Special hardening techniques produce a surface hardness similar to ceramic in the housing bores while maintaining elasticity that eliminates the danger of bore surface fracture. The hardening process of the rotor set includes PVD* treatment that results in a surface hardness of 1200HV. The Emtec pump is fully hydrodynamically balanced which eliminates thrust loads due to differential pressure. The power

rotor’s balance piston is extra long which improves the pump’s volumetric efficiency. Flow that crosses the balance piston serves to cool and lubricate the silicon carbide mechanical shaft seal faces. In applications where the “DQ” version is utilized, the shaft seal is eliminated to further reduce cost. Flow that passes across the balance piston is vented from the pump and into the reservoir. In this design, a labyrinth ring on the fluid side of the ball bearing prevents coolant “splash” from washing out the bearing grease.

Rotor Set

• Base material: Alloy steel

The “DQ” variant has all the features and benefits of the “D8.6” variant.

• Gas nitride hardened zone (62 HRC) • PVD hard coating: (1200 HV)

However, in place of the mechanical shaft seal, a shaft sealing ring is utilized and an axial inlet head is provided.

Housing • Ceramic-like bore surface (1200 HV) • Hardened transition zone (62 HRC) • Base material: Cast Iron rotor housing

The special material combination used for Emtec brings together the highest possible hardness with optimal elasticity and resistance to fracture.

Emtec: Extremely Variable in Installation For foot mounted, dry installations (easily accessible for maintenance), a silicon carbide mechanical shaft seal assures a long service life.

Emtec's unique center mounting flange allows for easy and economical tank-top installation with the discharge connection above the tank top.

Submerged tank mounting saves space, maintenance and costs compared with dry mount installation.

Horizontal or vertical (shaft up) “on-tank” eliminates the requirement for additional space on the pump skid.
