Hydra-Cell Pump D35-X

From the Hydra-Cell D35 series, this diaphragm pump is versatile enough for a variety of car wash applications, especially those that require large volume with high flow rates. The D35-X features a brass pump head, Buna-N diaphragm and O-rings, and 17-4 Stainless Steel valve and valve seats. It's highly recommended that you use a Hydra-Cell C-64 Regulator with this pump, especially with high pressure levels or when handling dirty fluids.

Features

• Pumps the full spectrum of low-to-high viscosity fluids.
  Features a seal-less design and horizontal disk check valves that enable the pump to handle abrasives and particulates that might damage or destroy other types of pumps.
• Able to run dry without damage (or additional maintenance) to the pump in case of accident or operator error.
• Tolerates non-ideal operating conditions. 
• Simple, compact design reduces initial investment and lowers maintenance costs.
• Operational efficiencies reduce energy costs.
• Minimizes maintenance and downtime because there are no mechanical or dynamic seals, packing, or cups to leak, wear, or replace.

How to Break Down the Full Part Number

D35 pumps use a 12-digit number for ordering purposes, with the last 9 digits signifying specific design and material information for the pump. For example, D35XKBTHFECA is the full manufacturer part number for this pump. This is how it breaks down:

• D35 - Series
• X - Hydraulic end cam specifications: Maximum flow rate of 36.5 GPM and 1050 RPM
• K - Pump head version: Kel-Cell NPT ports or ANSI flanges
• B - Pump head material: Brass
• T - Diaphragm and O-ring material: Buna-N
• H - Valve seat material: 17-4 stainless steel
• F - Valve material: 17-4 stainless steel
• E - Valve springs: Elgiloy
• C - Valve spring retainers: Celcon
• A - Hydra-Oil type: 10W30 standard duty oil

Common Car Wash Applications

• Prep Guns
• Wheel Blast Guns
• Tunnel High-Pressure Arches
• Reclaim Systems

How Long Does a Hydra-Cell D35 Last?

With regular oil changes, it will probably be 2-3 years before you need to do a diaphragm or valve job. With proper maintenance, oil changes, and use of a pressure relief valve, the pump will likely last about 10 years.
