Frequently Asked Questions about the KYOWA KYC-20A Oil-Free Pump (2.8/3.35 L/min):

A. General Overview
1/ What is the KYOWA KYC-20A?

The KYOWA KYC-20A is a compact, super-lightweight oil-free pump designed for cleaning applications. It employs a unique pumping mechanism (patent pending) that requires no lubrication oil or grease, minimizing maintenance needs and contamination risks.
2/ What do the flow rates 2.8 L/min and 3.35 L/min represent?

These figures correspond to the pump’s discharge performance at different power frequencies: approximately 2.9 L/min at 50 Hz (nominally 2.8 L/min) and up to 3.5 L/min at 60 Hz (nominally 3.35 L/min).
3/ What applications is the KYC-20A suited for?

Typical uses include air-conditioner cleaning, car engine-compartment washing, plasterers’ finishing, food-processing equipment sanitation, farm-tool and machine cleaning, insecting-machine maintenance, and steel-pipe degreasing.
B. Technical Specifications
4/ What are the pump’s dimensions and weight?

Dimensions: 250 × 210 × 230 mm (L × H × W) Weight: 9 kg
5/ What pressure and rotational speed does the pump deliver?

Maximum pump pressure: 40 kgf/cm² (≈ 560 psi) No-load speeds: 1,430 rpm at 50 Hz and 1,740 rpm at 60 Hz
6/ What motor type and power rating does it use?

Single-phase electric motor, 50/60 Hz, 250 W output
C. Key Features and Benefits
7/ What advantages does oil-free construction offer?
- Eliminates oil contamination of the target surface or sample
- Removes the need for regular oil changes and disposal
- Simplifies maintenance and reduces downtime
8/ What is the “JET CLEANPAK” mechanism?
- Differential operation: one suction stroke and two discharge strokes per cycle, stabilizing discharge flow
- Close-coupled design: no belts means no slipping or alignment issues
- Rolling-friction optimization reduces starting torque and boosts output efficiency
9/ How rugged and serviceable is the pump?

Its simple, all-mechanical construction allows for quick disassembly, straightforward cleaning, and easy reassembly—ideal for field and laboratory environments.
D. Operation and Maintenance
10/ How should I install the KYC-20A?
Place on a stable, level surface with adequate ventilation.
Ensure inlet and outlet hoses are free from kinks or blockages.
Confirm the power cord is plugged into a properly grounded outlet.

F. Troubleshooting Common Issues
15/ The pump isn’t starting. What should I check?
Verify power supply and fuse integrity.
Ensure the on/off switch is functional.
If the motor hums but doesn’t turn, seek authorized repair.
16/ The discharge flow has dropped significantly. What causes this?
Inspect the nozzle and hose for clogs.
Clean or replace the diaphragm and one-way valves if worn or torn.
17/ Why is the pump vibrating or making excessive noise?
Tighten all mounting bolts and check for loose components.
Worn diaphragms or valves may also create vibration—replace as needed.
18/ The unit overheats after prolonged operation. What can I do?
Maintain at least 10 cm of clearance around the pump for airflow.
Observe duty-cycle guidelines: allow periodic cool-down intervals during extended use.
