PULSAtron pumps from Pulsafeeder have a guided check valve system with a seat-and-ball design that ensures reliable and accurate metering year after year. Their fin-cooled solenoid enclosure dissipates heat, ensuring that the pressure-handling capability of the pump can be maintained. The thermally protected solenoid protects the pump from seizing up in extreme heat conditions with an automatic reset feature, allowing the pump to resume operation upon cooldown. They offer flows up to 600 gpd and pressures up to 300 psi, with a wide range of flows and pressures. 800/333-6677; www.pulsatron.com.
