Build and approvals
AISI 304 stainless steel stator shell with coated cast iron housings, a water and glycol mix cooling the thrust bearing, and a removable cable connector for quick service. Keep water moving past the motor at 1.0 ft/sec or better at 95 °F so it stays cool. Motor and cable are certified to CSA and UL, plus NSF 61 and 372 for drinking water. The all-AISI 316 4TWX is available on request. These are series figures; this model's own are on the spec sheet under Downloads.
