*Please note, these pumps are currently not in stock*

The Davies Pumps Classic SPK series pumps feature the original self-priming design, a model that has demonstrated its effectiveness over the past 50 years. This range includes motor pumps that are closely coupled, with an open impeller and a unique design for self-purging and fast self-priming, all specifically engineered for efficiency, dependability, and low maintenance over the years. These pumps, available in Cast Iron or Gunmetal Bronze, are versatile for a wide array of applications in agricultural, commercial, industrial, and marine environments.

The SP series pumps sport a semi-open impeller and a replaceable wear plate, enabling the pumping of small, soft solids without any blockages. The design of the pump casing retains sufficient water to self-prime and clear the suction line upon starting, though the use of a foot valve and strainer is recommended.

Key features of these pumps include a solid cast impeller, casing, and housing. They are available in either a corrosion-resistant Gunmetal or a robust Cast Iron construction. The pumps provide exceptional self-priming capabilities and a compact back pull-out design coupled with a front inspection plate. These design attributes contribute to lower maintenance needs and longer wear time. They can handle a maximum liquid temperature of 90 degrees, pump with flows up to 300 litres per minute and can generate pressure up to 53 meters. These pumps are proudly manufactured in New Zealand.

Self Priming Pumps

Positive priming. Minimum maintenance. Low cost. high Efficiency. These are the benefits of Davies Self-priming centrifugal design. Once initially primed, SP pumps retain enough water to ensure positive self-priming even though the suction line drains back to the source. Davies SP series pumps are self-purging to avoid vapour-lock.

Davies SPK Maintenance

The electric motor bearings are pre-lubricated at the factory and under normal conditions will not require attention. Should the pump fail to self prime check the following:

1. Insufficient water in the pump body.
2. Check the suction line for air leaks
3. Check the impeller, self priming port, and suction strainer are not blocked. The impeller and priming port are accessible by removing the cover plate on the front of the pump body.
4. Check for leaking seal, replace if necessary.
