Description

Wilden M15 / T15 — 3 Inch Aluminium Air-Operated Double Diaphragm Pump

1. Product Overview / 产品概述

The Wilden M15 (also known as T15, Turbo-FloSeries) is a3″ air-operated double diaphragm (AODD) pump with bolted aluminium wetted parts. Rated at 245 GPM (927 LPM) and 125 psi (8.6 bar), it is the workhorse of drilling fluid transfer, fuel handling and dewatering — no mechanical seal, self-priming, and it pumps dirty air without complaint.

4. Why Buyers Import This Pump / 采购理由

  • 48% lower ownership cost than the Pro-Flo SHIFT equivalent — no electronics to fail, no ADS diaphragm to replace.
  • Bolted (not clamped) design: higher pressure tolerance and thicker elastomer section than PS15.
  • Handles dirty, oil-laden air without an air filter — critical on rig sites.
  • 10 mm solids passage and 25,000 cps viscosity — takes mud, slurry and heavy crude.
  • Existing Wilden fleets run 15+ years; the housing outlives the pump, so M15/T15 is still a large installed base.

  4. Connection — 3″ NPT threaded (standard)
  5. Certification — ATEX, CE, or oil & gas project documentation if required

MOQ: 1 unit. OEM branding and custom colour available.

8. Installation & Commissioning / 安装调试

  1. Confirm air supply: 3/4″ NPT, minimum 125 CFM at 125 psi. Under-sized air is the number one cause of poor pump performance.
  2. Install a Filter-Regulator-Lubricator (FRL) unit — mandatory for any air-operated pump warranty.
  3. Use short, rigid suction pipe. Keep suction shorter than 15 ft and avoid loops.
  4. For vertical suction lift beyond 5 m, fit a foot valve or prime the pump manually.
  5. Anchor the pump on a base — 48 kg unit running at full stroke needs solid mounting.
  6. Commission at 50 psi, check for air leakage at all four tie rods, then raise to working pressure.
