AMT 285J-K5-SC/V Self-Priming Cast Iron Centrifugal Pump with WEG 00136ET3EJPRW56J-S Motor
The AMT 285J-K5-SC/V pairs a cast iron self-priming centrifugal pump with a WEG 00136ET3EJPRW56J-S 1 HP three-phase motor, giving facilities a rugged, ready-to-run unit for moving water and compatible liquids without a lot of fuss. The pump's dual volute design keeps radial load off the motor shaft, which translates into smoother running and longer service life, while the centerline discharge helps prevent vapor binding and keeps piping connections simple. A self-cleaning, semi-open impeller lets the pump handle liquids that aren't perfectly clean, and the unit will self-prime to about 20 feet, so it doesn't need to sit flooded to get going.
On the motor side, the WEG 00136ET3EJPRW56J-S brings the torque and reliability WEG is known for in a compact 56J footless, C-face frame. Running at 3600 RPM on 230/460V three-phase power, it's built TEFC (totally enclosed, fan cooled) so it can shrug off dust and moisture in a workshop, pump house, or utility room without extra enclosures. The stainless steel shaft and automatic-reset overload protection add a layer of everyday durability that keeps this pairing running with minimal attention.
Whether it's circulating water in a commercial process, boosting pressure for a washdown station, transferring liquid between tanks, or dewatering a low area, this AMT and WEG combination is sized to get the job done efficiently. It's equally at home in light industrial settings and demanding residential or agricultural applications, offering commercial-grade construction at a price point that doesn't require an oversized budget.

Frequently Asked Questions
Q: Can the AMT 285J-K5-SC/V run on standard single-phase household power?
A: No. This unit is built around a three-phase motor, so it requires a three-phase electrical supply. If only single-phase power is available, a comparable single-phase AMT pump model would be a better fit.
Q: What kind of liquids is this pump suited for?
A: It's designed for non-flammable liquids that are compatible with cast iron, Buna-N, or Viton seal materials, such as water, mild washdown fluids, and similar liquids used in general transfer or dewatering tasks. It is not intended for aggressive chemicals or flammable fluids.
Q: Does the pump need to be primed with water before starting?
A: Because it's self-priming, it doesn't need to be manually flooded each time, but the pump casing should have liquid in it during initial setup so it can draw the suction line up to about 20 feet on its own.
Q: How is this pump typically mounted?
A: It mounts on a base plate with bolt holes designed for standard foot-mount installation, allowing it to sit securely on a bench, skid, or platform close to the liquid source and discharge point.
Q: What maintenance does the motor need over time?
A: Routine maintenance is minimal thanks to the automatic overload protection and stainless steel shaft, but periodic checks of the seal, impeller clearance, and electrical connections are recommended to keep performance consistent over the long run.
