MARCH 893-13 Mag Drive Centrifugal Pump
Product Information
- Product: Series 893 Centrifugal Magnetic Drive Pumps
- Model Numbers:
- 893-13 (12V DC) – P/N: 0893-0072-0100
- 893-14 (24V DC) – P/N: 0893-0073-0100
- Description: The Series 893 pumps are centrifugal magnetic drive pumps that are hermetically encapsulated. They can only be used submerged in the liquid and require a flooded suction for operation. The impeller requires the liquid being pumped for lubrication, so the pumps cannot be run dry.
- Electrical: The brushless motors of the pumps have voltage protection. The red lead is positive, and the black lead is negative.
- Specifications:
- Inlet-Outlet: 3/8″ FPT-3/8″ OD
- Max Internal Pressure: 50 PSI (344 kPa)
- Max Liquid Temperature Submerged: 120°F (49°C)
- Max Flow:
- Model 893-13: 2.7 GPM / 11 LPM
- Model 893-14: 2.7 GPM / 11 LPM
- Max Head FT PSI M Voltage Electrical Amps HP: 10.6 / 4.5 / 3.3 / 12 / 0.85 / 1/150 / 0.004 / 4000 / 1.5 (for both models)
- Packed Weight: 1.5 Pounds (for both models)
- Materials in Contact with the Liquid: Noryl, Polypropylene, Carbon/Teflon, Buna N, 316 Stainless Steel, Epoxy, Delrin, Motor Leads
- Limited Warranty: March pumps are guaranteed against defects in workmanship or materials for one year from the date of manufacture when pumping water. For the complete warranty and online registration, visit www.marchpump.com/warranty-registration
Product Usage Instructions
- Ensure that the pump is fully submerged in the liquid before operation. The pump is hermetically encapsulated and can only be used submerged.
- A flooded suction is essential for operation. Make sure there is enough liquid available for the pump to draw in.
- Do not run the pump dry. The impeller requires the liquid being pumped for lubrication.
- For electrical connections, connect the red lead to the positive terminal and the black lead to the negative terminal.
- Refer to the specifications for the appropriate voltage and electrical requirements.
- Refer to the specifications for the maximum internal pressure, maximum liquid temperature submerged, and maximum flow rate for your specific model.
- Refer to the materials in contact with the liquid to ensure compatibility with the liquid being pumped.
- If you require application assistance or need further information, contact March Pump.
DESCRIPTION & OPERATION
Series 893 are centrifugal magnetic drive pumps. The 893-13 and 893-14 pumps are hermetically encapsulated which allows the pump to be run fully submerged, and the pumps can only be used submerged in the liquid. A flooded suction is essential for operation since the pump is not self priming. Pumps cannot be run dry because the impeller requires the liquid being pumped for lubrication. For application assistance, contact March Pump.
ELECTRICAL
The Brushless Motors have voltage protection. Red lead is positive, black lead is negative.
- Model 893-13 (12 VDC) starts at 5.5 V ± ≈0.5 V and turns off at 17.5 V ± ≈0.5 V.
- Model 893-14 (24 VDC) starts at 8.5 V ± ≈0.5 V and turns off at 28 V ± ≈0.5 V.
