Keep your water feature well-circulated with a Cal Pump Stainless Steel Pump. Cal Pump Stainless Steel & Brass pumps are specifically designed to meet the demands of any pond or water display. Unlike most other pumps on the market, Stainless Steel Pumps are designed to operate in fresh, salt, or chlorinated water and are also suitable for hot water applications up to 110 degrees Fahrenheit. Filled with biodegradable lubricant, rather than oil, these pumps cannot leak oil into the pond, which can be harmful or fatal to fish and plants. The pumps' 20 gauge stainless steel case, bronze pump body, and corrosion-proof fasteners, result in a durable, energy-efficient, and long lasting pump.
