Husky 1050 Air Operated Double Diaphragm Pumps

HUSKY 1050 SERIES — 1" DIAPHRAGM PUMPS

Air‑Operated • Electric Air‑Charged • High‑Pressure 2:1

Series Overview

• 1" diaphragm pump series with three variants:
  1050 (Pneumatic) • 1050e (Electric Air‑Charged) • 1050HP (High‑Pressure 2:1)

• Common fluid section architecture across all variants

• Wetted materials: Aluminum, Stainless Steel, Hastelloy, Polypropylene, Conductive Polypropylene, PVDF

• Elastomers: Buna‑N, Santoprene, Geolast, PTFE, FKM, Polychloroprene

• Self‑priming, runs dry, no rotating seals

• Handles up to 1/8 in (3.2 mm) solids

Key Features

• Low‑pulsation operation across all variants

  • Pneumatic: stall‑free modular air valve

  • Electric: air‑charged drive reduces pulsation without dampeners

  • HP: spring‑loaded pilots for fast changeover

• Extended diaphragm life

  • Up to 5× longer vs. competitive AODDs

  • Air‑charged drive (1050e) increases life

  • Additional diaphragm layer (1050HP) for high‑pressure durability

• Selectable performance modes (1050HP)

  • Operate as a standard AODD or a 2:1 high‑pressure pump

  • Low‑pressure mode reduces air consumption up to 50%

• Efficiency advantages

  • 1050: ~30% more efficient than market leader

  • 1050e: up to 5× energy savings vs. pneumatic

  • 1050HP: high pressure without sacrificing flow

• Serviceability

  • Externally serviceable pilots (air models)

  • Modular, lube‑free air valve (air models)

  • Shared wetted parts across variants reduce inventory

• Compliance & configuration

• ATEX configurations available

• Multiple motor/gearbox options for 1050e (AC, ATEX, XP, BLDC, NEMA, IEC)

Fluid Ports

• Metal Models (Aluminum, Stainless Steel, Hastelloy):

  • 1 in. NPT(F) or 1 in. BSPT(F)

  • Stainless steel center‑flange models available with 1 in. ANSI/DIN raised‑face flanges

• Plastic Models (Polypropylene, Conductive Polypropylene, PVDF):

  • 1 in. ANSI/DIN raised‑face flange

• Manifolds are reversible to change inlet/outlet orientation

• Unused ports are plugged where applicable

Mounting & Orientation

• Mount pump horizontally with feet at the bottom

• Ensure mounting surface supports pump weight and operational load

• Maintain clear access to air inlet, fluid inlet, fluid outlet, and air valve

• Avoid vertical or wall mounting

• 1050HP requires adequate air supply for high‑pressure mode

• 1050e requires clearance for motor/gearbox ventilation and wiring

Grounding

• Required when operating in hazardous, flammable, or static‑sensitive environments

• Metal pumps (Aluminum, Stainless Steel, Hastelloy) include a grounding screw for static discharge

• Plastic pumps (PP, CP, PVDF) only require grounding when used in applications where static buildup is a risk

• Ground air and fluid hoses when grounding is required

• 1050e models follow motor/drive electrical grounding requirements (per UL/CE), separate from static grounding

• Verify system continuity when grounding is used

Applications

• General Transfer: chemicals, solvents, coatings, inks, wastewater

• Shear‑Sensitive Fluids: paints, resins, specialty chemicals (1050e)

• Abrasive Slurries: ceramics, mining, wastewater solids

• High‑Pressure Requirements:

  • Filter press feed

  • Long hose runs

  • High‑pressure spray systems (1050HP)

• Energy‑Sensitive Facilities:

  • Plants reducing compressed‑air usage (1050e)

• Hazardous / ATEX Environments:

• All variants available with compliant configuration
