Wilden Introduces Pumps

Designed For Explosive,

Hazardous Environments

Effective immediately, Wilden

Pump & Engineering Co., Colton,

Calif., will offer electrically conduc- tive, graphite-filled Ml polypropy- lene models. These models have been introduced specifically for ex- plosive and hazardous environ- ments, where nonconductive plas- tics may be unacceptable due to static electricity discharge.

These graphite-filled models need to be earthed (grounded) at one connection, whereas virgin poly- propylene requires grounding at all clamp bands or connection points.

Surface resistance is less than 4 x 10

Ohm, thus providing adequate dis- persal of static electricity discharge when pumping nonconductive liq- uids.

These pumps offer the same ad- vantages as all Wilden air-operated, double-diaphragm pumps: no mo- tors, no seals, no packing, run dry capability, variable speed, variable pressure, explosion resistant, and self priming.

The Marine Machinery Associa- tion (MMA) has announced that the

Defense Advanced Research Project

Agency (DARPA) and the MMA will jointly sponsor a Research and

Development Seminar on Novem- ber 29,1989, at the Key Bridge Mar- riott Hotel in Arlington, Va. This seminar is intended to assist naval machinery manufacturing compa- nies in getting involved with the

R&D of new equipment for subma- rines.

Speakers will be present from

DARPA's Naval Technology Pro- gram, as well as from NAVSEA, and the Naval Research Center. A high- light of the program will be an R&D

Forum to include representatives from industry and the naval re- search community.
