Taco 111-8 Cast Iron Pump 1/12 HP

Zoned residential hydronic heating can evaluate the Taco 111-8 Series 111 circulator with 1/12 HP power, cast-iron construction, resilient-mounted oil-lubricated motor, and flanged connection options from 3/4 inch through 1-1/2 inches.

The cast-iron body is identified for hydronic systems only, so the product should not be presented as a potable-water circulator without separate material approval. Its oil-lubricated drive requires accessible maintenance space, while the supplied record does not state exact voltage, flow, head, pressure, or temperature.

Technical Details

- The 1/12 HP motor establishes the listed power class for residential hydronic planning.
- Cast-iron construction identifies the body material for closed hydronic system use.
- Flanged connections from 3/4 to 1-1/2 inches support replacement fitment evaluation.
- A resilient-mounted motor identifies the documented drive arrangement for installation review.
- Oil lubrication creates a recurring maintenance requirement for service planning.
- Zoned residential hydronic heating defines the stated application context.

Performance and Application

The Series 111 is listed for zoned residential hydronic heating, but the supplied product record does not state exact flow, head, NPSH, pressure, temperature, pump curve, or efficiency values. The connection range supports dimensional screening, while actual circulator selection must follow system resistance and required heat-transfer flow.

Installation Requirements

Confirm the selected flange size, flow direction, motor voltage, installation orientation, oil-access clearance, fluid temperature, system pressure, and cast-iron compatibility before startup. Because the body is designated for hydronic systems only, potable-water use requires a different material classification and documented application approval.

Warranty and Maintenance

Taco 00 Series warranty language does not automatically establish coverage for this Series 111 model, so a separate named warranty term is not stated. Periodic oil lubrication remains a documented maintenance requirement. Mulmotor can assist with product details, replacement questions, and order-related support before purchase.
