Product catalog summary

Product Overview

The document describes the Jabsco Models 11810-0121 and 11810-0241 self-priming pumps designed primarily for marine applications such as bilge pumping, bait tanks, wash downs, and general marine service.

Specifications

  • Construction: Bronze pump body, neoprene impeller, stainless steel shaft with stainless steel impeller sleeve, replaceable wearplate, lip-type shaft seal.
  • Ports: Both 3/4" garden hose external thread and 1/2" internal pipe thread.
  • Motor: 1/3 HP, 1800 RPM, continuous duty; available in 12V DC (Model 11810-0121) and 24V DC (Model 11810-0241).
  • Weight: Approximately 22 lbs (10 kg).
  • Electrical Compliance: Meets USCG ignition protection standards for gasoline-powered vessels.

Performance and Operating Parameters

  • Self-Priming Capability: Suction lift up to 10 feet when dry, up to 22 feet when primed. Suction lines must be airtight for proper priming.
  • Maximum Continuous Head: 40 feet total developed head.
  • Flow Rates at 1800 RPM: Ranges from 8.1 to 11.2 GPM (30.7 to 42.4 LPM) depending on head pressure (10 to 40 feet).
  • Running Dry: Pump must not run dry for more than 30 seconds to avoid impeller damage.
  • Temperature and Fluid Compatibility: Avoid pumping solvents, thinners, or highly concentrated/organic acids. Flush pump with water after handling corrosive fluids to prolong life.

Installation and Operation

  • Mounting in any position is possible; vertical mounting with pump head down is recommended.
  • Direct drive only.
  • Motor rotation determines intake and discharge port locations; refer to dimensional drawings.
  • Wiring must follow specified wire gauge to prevent voltage drop; strain relief connectors are recommended to secure wiring.
  • For correct clockwise motor rotation, connect positive lead to terminal A1 and negative to A2.
  • Switches controlling the pump must have amperage ratings equal to or greater than the recommended fuse size.

Models 11810-0121, 11810-0241 VARIATIONS AVAILABLE model no. description Motor meets USCG Electrical Standards (Title 33, Chapter 1, Part 183; Subpart 1) for ignition protection on gasoline powered vessels. APPLICATIONS Ideal for Bilge Pumping, Bait Tank, Wash Downs, and General Marine Service. OPERATING INSTRUCTIONS 1. INSTALLATION - Pump may be mounted in any position without loss of efficiency; however, it is suggested that the pump head be down if vertical mounting is desired. The rotation of the motor shaft determines the location of the pump’s intake and discharge ports. Refer to the Dimensional Drawing. 2. DRIVE - Direct. 3. SELF-PRIMING - Pump will produce a suction lift approaching 10 feet when dry and a lift up to 22 feet when primed. BE SURE SUCTION LINES ARE AIR TIGHT or pump will not self-prime. 4. RUNNING DRY - Unit depends on liquid pumped for lubrication. DO NOT RUN DRY for more than 30 seconds. Lack of liquid will burn the impeller. 5. NOTICE - Do not pump solvents, thinners, highly concentrated or organic acids. Pump damage may result. If corrosive fluids must be handled, pump life will be prolonged if pump is flushed with water after each use or after each work day. 6. PRESSURES - For continuous operation, do not exceed 40 feet total developed head. 7.
