VR Series vertical, stainless steel multistage pumps from Franklin Electric deliver clean water under pressure. These booster pumps are available with a flow range up to 600 gpm and 750 feet total dynamic head. Each has all 316 stainless steel hydraulic components for durability, efficiency and performance in corrosive water applications. Impellers and diffuser stages are fabricated from heavy-gauge stainless steel. The oversized ball bearing/coupler assembly eliminates the need for stack height adjustment and supports the axial thrust load. The elimination of axial thrust allows the pumps to use industry-standard motors instead of the high-thrust motors. 800/701-7894; www.franklinwater.com.
