Split Case

Type KP (Horizontal Split Case)
Type KPV (Vertical Split Case)
Type KPVS (Vertical Split-coupled Split Case)

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

The KPVS split-coupled split case pump reduces the mechanical space footprint with its vertical motor arrangement, provides easy access to seal and internal components without ever needing to remove the motor, and needs no field alignment.  The new KPVS also includes all the benefits of a double suction/double volute splitcase design – reduced radial loads mean less noise and vibration while the between bearing design is more robust and greatly reduces vibration.

Features and benefits

KP Horizontal Split Case pump

• > 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

KPV Vertical Split Case pump

• > Vertically mounted design for space savings
• > Lower sleeve bearing with liquid cooled design facilitates leak free performance and reduces maintenance costs
• > Machined rabbet fit design aligns the vertically mounted motor and pump, thus removing the need for alignment
• > 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

KPVS Vertical Split-Coupled Split Case pump

• > Vertically mounted design for space savings
• > Easy access to the shaft seal with the split coupling and removable bearing housings
• > Pump stand to hold the weight of the pump
• > Rigid coupling design to eliminate the need for field alignment
• > Reduced overall footprint (flange to flange) when compared vertical inline pumps, meaning the smallest footprint in the space
• > Double suction minimizes axial load, which extends the life of the wear rings and shaft seal
• > 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
