Udor KAPPA-43 Diaphragm Pump with Pressure Regulator – 10.5 GPM
Udor KAPPA-43 – Professional Three-Diaphragm Replacement Pump
The Udor KAPPA-43 is a commercial-grade diaphragm pump designed for spraying applications that demand reliable flow, adjustable pressure, and long-term serviceability.
With a maximum output of 10.5 gallons per minute, the KAPPA-43 is well suited for professional lawn-care equipment, tree and shrub sprayers, agricultural spraying systems, nursery applications, and pest-control operations.
Durable Three-Diaphragm Construction
The KAPPA-43 features a three-cylinder, positive-displacement diaphragm design with internally manifolded construction.
Its anodized-aluminum pump body and anodized-aluminum and stainless-steel liquid-handling components are designed for use with compatible agricultural, horticultural, and turf-care chemicals.
Standard GREENTECH diaphragms provide dependable operation and can be replaced using genuine Udor repair kits.
Adjustable Pressure Control
The KAPPA-43 replacement configuration includes a pressure-control assembly with an adjustable pressure regulator, manual dump lever, two ball-valve discharge outlets, and pressure gauge.
This allows operators to adjust system pressure for the spraying application and unload the pump through the bypass when required.
Ideal for Existing KAPPA-43 Installations
This model is commonly purchased as a replacement for an existing KAPPA-43 pump when the original gear-reduction unit is still operational.
The KAPPA-43 does not include a gas-engine gearbox. Customers replacing a pump connected to an existing gearbox must confirm the shaft configuration, mounting arrangement, and gearbox compatibility before installation.
Customers requiring a complete gas-engine gear-reduction assembly should select the appropriate KAPPA-43/GR model instead.
