WHEN TO USE A RECIPROCATING PUMP

  • High pressure with low flow
  • Variable flow with constant pressure
  • Constant flow with variable pressure
  • High efficiency required

MAIN ADVANTAGES

Reciprocating Pumps:

  • Fixed flow per revenue
  • Flow is independent of pressure
  • Pressure is independent of flow
  • High efficiency

Centrifugal Pumps:

  • Varying flow per revenue
  • Flow is pressure dependent
  • Pressure is flow-dependent
  • Low efficiency

ALDRICH Reciprocating Plunger Pumps are inherently designed for reliable high-energy, heavy-duty service in specialized applications. Meeting

API 674 design and performance criteria, each pump is engineered to provide continuous-duty operation over a 20-year design life. Offering a wide variety of hydraulic, mechanical, and materials options, ALDRICH Reciprocating Plunger Pumps can be constructed to meet the specific characteristics of the most demanding applications, including abrasive slurries and high viscosity liquids. This results in maximum operating flexibility with minimum life cycle costs.

PUMP CUSTOMIZATION

The ALDRICH engineered Reciprocating Pumps offer users a wide range of options to customize a solution for mission-critical pumping needs.

The ALDRICH Reciprocating Pump product line provides maximum operating flexibility. Available in horizontal and vertical configurations and customer-specific materials. ALDRICH reciprocating pumps are engineered individually to meet the application's actual performance and installation requirements while reducing maintenance and replacement costs.

KEY FEATURES

Liquid end Design Options

Depending on the application, ALDRICH plunger pumps use different pump ends and corresponding cylinder designs. The slurry pump end has been specially developed for pumping media containing solids such as minerals, ores, overburden, and coal. The solids' content can be up to 60 % by weight.

Pump cylinders with a minimum of clearance volume are the economical solution for pumping liquid gases such as ammonia, CO2, LNG, and LPG. Minimizing the clearance volume is an essential method for improving the volumetric efficiency of pumping compressible media. This applies not only to process pumps but also to secondary recovery into caverns and oil fields.

Design of the Cylinder Block

The monobloc construction of the cylinder block is convincing due to its high operational reliability. This one-piece construction with internal suction and discharge channels ensures individual accessibility to the valves without disconnecting suction and discharge connections.

The multi-part design of the cylinder block is designed for exceptional operating conditions, such as very high media temperatures. Suction and discharge manifolds connect the individual cylinder blocks. Depending on the requirements, forged or cast cylinders are built-in.

Stuffing Boxes

The stuffing box designs are adapted to the different media. Plungers in different material designs matched to these media contribute to the reliable operation of the machine.

Valves

A wide range of different valve variants in ball, plate, cone, or plug design is available for the various applications, ensuring reliable, low-maintenance operation.
