PACO End Suction Pumps: LC, LF
Type LF (Frame Mounted)

Type LC (Close Coupled)

Type LCV (Vertically Mounted Close Coupled)

The PACO line of end suction, single stage pumps serves as the industry standard in performance, quality, and durability. With an expanded selec­tion of 32 sizes available, the PACO line of pumps is the smart choice for a number of reasons:

  • Low life-cycle costs
  • High efficiency for reduced operation costs
  • Compensated double-volute design for reduced radial loads, minimized shaft deflection, and prolonged seal life and bearing life
  • Mechanical design for reduced maintenance and minimal downtime
  • Back pull out design for ease of maintenance and servicing
  • Range of sizes to meet precise application requirements
  • Quiet operation

Advanced features incorporated as standard on PACO end suction pumps ensure optimum perfor­mance and reliability. These features, as well as optional features that meet specialized needs, are available on the broadest line of high-efficiency pumps offered to the industry.

An innovative pump and impeller design produces a higher operating efficiency – up to 91 percent – and provides a wider band of best operating efficiency, even during conditions of off-design operation.

Quite simply, the PACO line of pumps is the smart choice for lower initial cost, longer pump life, re­duced operating and maintenance costs, maximum reliability, and quieter operation.

PACO Horizontal Split Case Pumps: KP

4The PACO KP/KPV split case pump is a single-stage, non-self-priming, between bearing, centrifugal volute pump. The axially split design allows easy removal of the top casing and access to the pump components (bearings, wear rings, impeller, and shaft seal) without disturbing the motor or pipe work.  The pump is available in horizontal (KP) and vertical (KPV) configurations.

The independent bearing housing allows for ease of maintenance without removing the top casing. The double volute design reduces the radial load on the shaft, extending component life, minimizing vibration and providing quiet operation.

The KP/KPV pump also offers high pump efficiencies throughout the range. High energy efficiency along with long pump life and easy maintenance add up to low life-cycle costs.

The KPV pump is available with a liquid cooled sleeve bearing which promotes longer life and reduces maintenance.

The KP/KPV pump is ideal for custom applications and is available in a wide range of variants. The high efficiency and low life cycle costs make the KP/KPV ideal for any commercial building, water utility or industrial projects.

Features and benefits

    • Easy to service: split case design
    • Double suction minimizes axial load, which extends the life of the wear rings, shaft seals and bearings
    • Double volute reduces radial forces and minimizes noise and vibration
    • Independent bearing housing design allows access to the pump components without removing the top half of the casing
    • Suction baffles reduce losses and improve NPSH-R by directing flow into the eye of the impeller
    • High energy efficiency
    • Low life-cycle costs
    • Many product variants available

 

 

PACO Vertical Inline Pumps: VL, VLS

VERTICAL INLINE

Type VL (Close Coupled)5

Type VLS (Split Coupled)

** Introducing NEMA TC frame motors on PACO VLS pumps **

  • Significantly Improved Lead Time
  • Increased Ease of Service
  • Greater Customer Value

 

The PACO VL/VLS series of Grundfos pumps are part of the SMART family of pump products which are better engineered to increase efficiency and reduce radial loads. SMART pumps are also designed to help reduce operating and maintenance costs.

The VL/VLS Inline pumps have proven to be extremely versatile, often exceeding the requirements for a variety of market applications, such as chilled water, condenser water, and hot water systems.

WHAT’S YOUR INSTALLATION FOOTPRINT?

When floor space is a consideration, you’ll want to go with the VL. Where many other pumps might not fit, the VL’s vertical inline mounting guaran­tees the smallest footprint, literally requiring no floor space.

INNOVATIVE DESIGN FOR OPTIMUM OPERATION

Grundfos pushes the limits of pump perfor­mance. The VL offers comprehensive sizes and configurations to meet your needs. It has a supe­rior hydraulic and mechanical design, which pro­duces higher efficiency, reduced pump noise, and longer pump life.

The VL can be fitted with a speed-control system, which significantly cuts energy use and provides a pump payback in as little as one to two years.

Features and benefits

    • Saves floor space and reduces piping
    • No flexible connectors or foundation grouting needed
    • Mounts like a valve for quick installation
    • No coupling alignment or bearing frame assembly needed
    • Equal Size Suction and Discharge Pipes – no need for reducers or other fittings
    • Easier to maintain and smaller spare parts inventory
