Vertex 3 Gallon COOLANT Pump KIT
The Vertex 3 Gallon COOLANT Pump KIT provides portable cooling for drilling and milling machines, small lathes, and other equipment needing coolant. It features a 110V, 1/8 HP motor and is designed for quick deployment in workshop settings. Its compact size supports temporary or mobile cooling setups, while maintaining reliable flow for moderate-duty machining tasks.
Vertex 3012-8122 Deep Under Water Coolant Pump
This deep-underwater coolant pump delivers robust circulation for industrial machines. The 1/8 HP motor handles continuous operation with a corrosion-resistant design and anti-rust coating. The unit is designed for reliability in submerged or submerged-adjacent cooling configurations in machine tools requiring steady coolant flow and pressure.
Little Giant PE-1 Submersible Pump
The Little Giant PE-1 is a versatile 115V, 1/125 HP submersible pump suitable for machine tool coolants, water transfer, and display applications. Its epoxy-encapsulated motor and rotatable volute (90°) simplify installation in tighter spaces, while the polypropylene impeller and screen protect components from debris and wear. The pump accommodates multiple orientations as long as the liquid remains above the intake.
Little Giant 1-A Submersible Pump
The Little Giant 1-A is a compact 115V, 1/200 HP pump designed for machine tool coolants and other water transfer tasks. It features an epoxy-coated aluminum housing, an oil-filled motor for durability, and a screened inlet to reduce debris damage. A 6-foot power cord and sturdy construction make it suitable for workshop setups where space is at a premium.
AMT Pump 5381-95 Immersion Coolant Pump
The AMT Pump 5381-95 is an immersion coolant pump with a cast-iron body and 1/8 HP motor. It is designed to withstand industrial coolant environments and features a sealless design with a stainless steel impeller. Its robust construction makes it a suitable choice for machine-tool coolant circulation in harsher workshop conditions.
CNZG PNEU Coolant Mister
The CNZG PNEU coolant mister provides spray-based lubrication and cooling for milling, turning, and grinding operations. Although not among the five chosen sections due to catalog variability, it offers targeted mist coolant delivery with a magnet base for easy positioning on CNC equipment, aiding cutting speed and tool life in certain setups.
OEMTOOLS 24938 Pneumatic/Manual Fluid Extractor
The OEMTOOLS 24938 is a dual-operation fluid extractor that can remove coolant, oil, or other fluids via dipstick tubes or direct openings. While not a dedicated coolant pump, it can support maintenance operations around coolant systems by enabling quick fluid removal and transfer in workshop environments.
TTC IMP553-1 Immersion Coolant Pump
The TTC IMP553-1 is an immersion coolant pump rated at 1/8 HP with 115/230V compatibility. Its compact dimensions and immersion design suit machine-tool setups that require direct immersion in coolant reservoirs to ensure reliable circulation and heat removal in moderate-duty tasks.
Buying Guide: Key Purchase Considerations
- Duty cycle and reliability: Consider pumps rated for continuous operation in a workshop environment. Look for corrosion-resistant coatings and materials that tolerate coolant exposure.
- Voltage and compatibility: Ensure the pump voltage matches your workshop power supply (most options here are 115V). Check phase compatibility for available power sources in your facility.
- Submersible vs. inline: Submersible pumps are common for bulk coolant circulation, while inline or deep-underwater models suit deeper reservoirs or certain machine configurations. Assess space, reservoir depth, and flow needs.
- Flow rate and head: Evaluate gallons per hour (GPH) and hydraulic head to ensure the pump delivers adequate flow to your tooling without creating excessive turbulence or splashing.
- Material and build quality: Cast iron, epoxy coatings, and corrosion-resistant housings extend service life in coolant environments. A robust impeller and screened inlet protect against debris.
- Maintenance and service: Look for pumps with accessible seals and replacement parts. A unit with a straightforward maintenance schedule reduces downtime.
- Installation flexibility: Rotatable or adjustable outlets, 6-foot cords, and compact footprints simplify mounting and integration into existing tool setups.
In choosing among these options, balance the required flow rate, reservoir depth, and space constraints with the durability and warranty considerations typical of professional machine-tool coolant systems. For deeper-underwater or industrial use, Vertex and AMT Pumps offer robust, corrosion-resistant designs. For compact, versatile tasks and easy installation, Little Giant models provide flexible positioning and straightforward maintenance. The TTC and CNZG PNEU selections add niche capabilities for immersion and mist-based cooling, respectively, expanding options for specific machining workflows.
