Type ESC Single-StageEnd-Suction Direct-Coupled Centrifugal Pumps

Acme type ESC direct-coupled centrifugal pumps are of single-stage end-suction design suitable for handling water, chemicals and other liquids. They are available in cast iron and a range of corrosion resistant stainless steel. They are widely used in building services,water supply and treatment, sprinkling and irrigation, drainage, liquid transfer, food, chemicaland other general industrial applications.

16 bar working pressure as standard with optional casing working pressure up to 20 bar requires robust and solid construction to ensure durability even under high suction pressure condition.

Back-pull-out construction allows rotating assembly to be withdrawn without disturbing the suction and delivery connections.

Double volute design available for selected pumps. It eliminates radial load by balancing the hydraulic force of liquid within the pump casing, extends seal and bearing life and minimizes vibration and noise.

DIN 2533 ND/16 suction and delivery flanges connections to meet the design working pressure rating.

Use standard IEC foot and flanged electric motor to provide rigid mounting for the complete pump unit. Close-coupled design saves floor space and provides for easy installation and maintenance.

Mechanical seal with silicon carbide rotating element against carbon as standard. Other materials are available to meet specific requirements.

Vertical-in-line mounting available as an option to save floor space and provides for easy installation of piping.

Excellent parts interchangeability reduces inventory level for spare parts.
