The TRIVAC B is the logical step

ahead within the well-proven TRIVAC

concept. Here the performance and

the characteristics of the pumps have

been adapted without compromise to

market requirements. The TRIVAC B

pumps with their comprehensive range

of accessories have proven themselves

time and again as rugged pumps in

many and varied applications.

The inner body is assembled from

individual parts without sealing components.

The parts are pinned in order

to ensure easy disassembly and reassembly

of the parts.

All pumps from the D 4 B to the

D 25 B model are equipped either

with single-phase or three-phase

motors. D 40 - 65 B models are

equipped with three-phase motors.

Moreover, all pumps of the B series

are available also without the motor.

In the TRIVAC B, the pump unit and

the motor are linked by an elastic

coupling.

The TRIVAC B range is a modular

system which divides into three

groups:

- All basic models (single-phase and

three-phase motor) are certified in

accordance with 94/9/EG (ATEX)

(Category 3 inside)

- High water vapor tolerance

- Continuous operation even at

1000 mbar

- Built-in oil pump; pressurelubricated

sliding bearings

- All controls as well as the oil sight

glass are located on the front face

- Either vertical or horizontal intake

and exhaust ports

- Exchangeable inner body

- Anti-suckback valve controlled via

the oil pressure

- Free of yellow metals

- Service-friendly

- Ideal as backing pump for medium

and high vacuum applications,

because of low oil backstreaming

- Highly leaktight (He-3-capable)

Small flanges, centering and clamping

rings. The intake flange contains a dirt

trap.

A carrying handle is standard for all

pumps up to the D 25 B. TRIVAC B

pumps with single-phase motors are

delivered with ON/OFF switch, main

cord and main plug, ready for immediate

operation.

Standard TRIVAC B pumps come with

a filling of N 62 special oil (HE-200 in

the U.S.), others with special oil fillings

can be specified.
