ALLHEAT®

ALLHEAT® In-Line Design NIWH, CIWHALLHEAT® Series Centrifugal Pumps

The ALLHEAT® series centrifugal pump was designed spe-cifically for safe pumping of hot fluid medias. This versatile and universally applied pump series offers the best techni-cal solution at an excellent price for pumping mineral and synthetic thermal oils at temperatures up to 660oF or hot water up to 400oF. The main features this product brings to the marketplace include:

• Low Viscosity Capability (0.2 centistokes min.)

• Safety Packing Rings to isolate contaminates

• Excellent Price/Performance Ratio

• Robust mechanical design with stiffening ribs

• Patented large oil reservoir for the mechanical seal including a patented seal chamber gas venting system

• No additional cooling required for the seal chamber or bearings

• Interchangeable internal parts for foot mounted, block and in-line designs

• High efficiency impeller/casing combination

• Available with balanced or unbalanced mechanical seals

• Insert kits available to upgrade older NTT, CTT series thermal oil pump designs

• Long life and low maintenance sleeve in-board journal bearings

• Long life, permanently greased, sealed outboard roller bearing

• Double cardanic couplings for high temperature misalignment protection and ease of insert removal

Block Design(Integrated pump and motor-Series NBWH & CBWH)

Foot Mount(Series NTWH & CTWH)

Inline Design (Integrated vertical or horizontal pump and motor-Series NIWH & CIWH)

The ALLHEAT® concept is also available in a space sav-ing block and in-line design. The drive motor is flange mounted directly to the pump. The ALLHEAT® in-line pump can also be simply installed into the piping system without any need for a separate support.

• Available in foot mount pump-to-motor (NTWH or CTWH) or integrated pump to motor designs (NIWH or CIWH). (NBWH or CBWH) as shown above.

• Integrated pump-motor design (NIWH or CIWH). (NBWH or CBWH), includes an integrated seal chamber, cooling fan, and integrated motor shaft cou-pling

• Carbon journal bearing on a steel shaft with a non-bal-anced mechanical seal for thermal oil viscosities as low as 0.2 centistokes and temperatures up to 660oF or for hot water up to 360oF

• Sintered Silicon Carbide (SSiC) journal bearings and balanced mechanical seal for hot water applications exceeding 360oF to as high as 400oF or for highly con-taminated thermal oil applications

ALLHEAT® pumps have been rigorously tested during continuous fac-tory tests carried out on ALLWEILER’s thermal oil and hot water test stand and during practical tests carried out in selected customer’s plants since 2000 and 2001 respectively.
