FOUR & FIVE STAGE PUMPS
FLOWS TO 94 GPM; PRESSURES TO 365 FT

ECH4     ECH5
   
   
   
APPLICATIONS: For continuous heavy-duty chemical transfer or process service where high head and corrosion resistance are required.

DESIGN: High-efficiency, low-NPSHR end suction with a closed impeller close-coupled to mount to any standard 143/5TC or 184C motor. Pump is also available power frame mounted. Teflon O-ring seals. These heavy-duty units handle flows to 94GPM at high pressures under severe operating conditions. Impellers and stages are precision cast for high strength and chemical resistance. Maximum standardization of parts minimizes and simplifies maintenance.

SEAL: Type 21 mechanical rotary seals with carbon, Viton, and ceramic are standard on all 316 stainless steel pump models. Type 9 seals with chemical-grade carbon, Teflon and silicon carbide are optional on 316 stainless steel models and standard on Alloy C models. Double Type 9 seals are available in the same materials.
