BETE CLUMP Tank Washing Nozzles

Clog-Resistant Stationary Tank Cleaning Devices

Tank Washing Nozzle, Drum Washing Nozzle and Bottle Washing Nozzle

The Bete CLUMP is an assembly of Bete MaxiPass nozzles in a manifold providing omni-directional coverage similar to the Bete LEM. The CLUMP provides an even spray pattern and a larger free passage. It’s peak performance is at 10-30 psi (1-2 bar) and can fit through openings 4.75′ and 575′ (37.4mm and 146mm). Stationary nozzles, such as the CLUMP spray head, are characterized
by a particularly large cross-section. In addition, these nozzles are extremely low maintenance.

Design Features of the Bete CLUMP Spray Nozzle:

– Each tank washing nozzle in the stationary cluster is a BETE clog-resistant full cone nozzle of the MaxiPass series

– Can be supplied with various other BETE nozzles for any desired application

– Female connection

– Symmetrical spray make them more suited to short tanks, full 360° washing

– Very large free passage

Spray nozzle heads for industrial tank cleaning, drum, and tote washing

Six clog-resistant MaxiPass® full cone nozzles arranged in a cluster to project spray in all directions

Spray Characteristics of the Bete CLUMP Spray Nozzle:

– Spherical omnidirectional coverage

– Six nozzles arranged in cluster to project spray in all directions
